Modern agriculture has caused extensive soil pesticide contamination, which is a global concern. This study explored the potential of bamboo charcoal (BC) to alleviate quinclorac-induced stress in tobacco plants. A pot experiment was conducted to investigate the effects of BC and vinasse fertilizer (VF) on the growth and physiological parameters of tobacco plants subjected to quinclorac stress. At 30, 60, and 90 d after transplantation, BC and VF exhibited pronounced restorative effects on quinclorac-stressed tobacco plants. The treatments improved plant height, leaf length, and leaf width, and enhanced leaf quality and various biochemical indicators. Treatment with 500 g VF + 4% BC resulted in the lowest residual quinclorac levels in both the soil and leaves. Treatment with 500 g VF + 2% BC resulted in the most significant recovery of agronomic traits, whereas 500 g VF + 0.5% BC was the most effective in enhancing leaf quality. However, the effectiveness of BC decreased with time following application, and furthermore, quinclorac may be released from the BC. In conclusion, BC shows promise in alleviating the adverse effects of quinclorac stress in tobacco plants.

Chitosan–montmorillonite bionanocomposite (CTS–MMT) was prepared for removing the herbicide quinclorac (QC) from aqueous solution. The resulting nanocomposites were characterized by X-ray powder diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), Brunauer–Emmett–Teller (BET) surface area and Barrett–Joyner–Halenda (BJH) pore size distribution analysis. The adsorption of QC onto CTS–MMT as a function of adsorbent dosage, pH, temperature, ionic strength, contact time, and initial QC concentration was investigated by conducting batch adsorption experiments. The results showed that CTS–MMT exhibited higher adsorption affinity and higher adsorption capacity towards QC than the unmodified montmorillonite. The adsorption kinetics data of QC onto CTS–MMT were well described by the pseudo-second-order kinetics model. Adsorption isotherms fitted well with the Freundlich isotherm model in the heterogeneous adsorption process. Adsorption thermodynamics study indicated that the adsorption of QC onto CTS–MMT was a spontaneous and endothermic process. The QC molecules on CTS–MMT could hardly be desorbed by water, but could be desorbed by 0.1 mol/L NaOH solution. QC adsorption on CTS–MMT may involve electrostatic attraction, cation–dipole, hydrogen bonding, and van der Waals interactions. The findings of this study suggest that CTS–MMT is a potential adsorbent for quinclorac pollution remediation.

To explore highly effective and nonmetallic advanced oxidation process system to alleviate the persistent herbicides contamination in agricultural soils is of great importance. In this study, a significantly graphitized biochar with abundant C = O structure is prepared as non-metallic catalyst (WCGBC800). Different from other traditional amorphous pristine biochar, WCGBC800 can accelerate the electron transfer in the system and then effectively activate peroxymonosulfate (PMS) to produce free ( OH, O 2 – , SO 4 − , etc.) and non-free radicals ( 1 O 2 , electron transfer, etc.). Consequently, WCGBC800 can degrade 100 % the persistent organic herbicide quinclorac (QNC, with a content of 50 mg·kg −1 ) in soil within 20 min after PMS addition. The T.E.S.T-QSAR software simulation evidence that the toxicity of degradation intermediates is much lower than QNC. The stress of QNC on rice seedlings was directly described through rice cultivation experiment. The stress of rice seedlings was relieved after WCGBC800 + PMS treatment. The growth experiment of rice seedlings also shows that with an original QNC concentration of 7 mg·kg −1 in soil, the root length, root surface area, leaf length, leaf area, and leaves perimeter of rice increase of 255.30 %, 148.38 %, 207.64 %, 204.19 %, and 63.69 % respectively after detoxification by WCGBC800 + PMS system. This functional material and the WCGBC800 + PMS system provide new solutions for solving the problem of herbicide residues in soil with promising safety.

Exploring catalyst materials which are advancing, recyclable and with high catalytic performances to remove persistent organic pollutants such as Quinclorac (QNC) is important. In this work, a novel N-doped carbon support CoFe 2 O 4 /Fe 0 hybrid catalyst (CFO/Fe@C) was in situ formed by a simple co-precipitation and calcination process. Fine intergrowth crystal CoFe 2 O 4 and Fe 0 were uniformly dispersed on the N-doped porous carbon that derived from the raw material Ethylene Diamine Tetraacetic Acid (EDTA), which also provided chelating effect to prevent the agglomeration of the metals. Interestingly, the Fe 0 could only be formed with the presence of cobalt, possibly due to the increased reduction property resulted from the particle refinement. The as-formed Fe 0 could not only activate the peroxymonosulfate (PMS) but also reduce the Co 3+ , resulting in a synergistic impact to remarkably enhance the degradation performance. Besides, the N-doped porous carbon can also benefit the degradation of pollutant by strengthening the electron transfer. A good degradation efficiency of QNC was obtained in CFO/Fe@C-PMS system and most of the QNC had been degraded to carbon dioxide , water and other small molecular organisms. The removal rate remained over 70% after four reuses and the material could be easily recovered from the solution due to the good magnetic properties. Therefore, the as-prepared CFO/Fe@C catalyst should be an ideal catalyst for the removal of organic pollutants .

Highly selective herbicide quinclorac (Qui) is a type of quinoline carboxylic acid hormone herbicide, which has the characteristics of long half-life and difficulty for degradation, causing high risk to the environmental safety. In this study, anti-Qui 8A3 monoclonal antibody (mAb) with good specificity and high affinity (3.89 × 10 9 L/mol) was prepared, and two kinds of lateral flow immunochromatographic strips (LFICS) including nano-flower nanoparticles (AuNF) - and latex microsphere (LM)- based LFICS were established based on the antibody and signal amplification. The linear range of the AuNF- and LM- based LFICS were 5.31–345.48 ng/mL and 2.52–257.92 ng/mL, respectively. The limit of detection (LOD) of the AuNF- and LM- based LFICS were determined to be 5.31 ng/mL and 2.52 ng/mL, respectively. In summary, the developed LFICS using AuNF and LM as signal amplification reporters exhibited excellent sensitivity and provided the rapid on-site screening of Qui and other analytes in food safety field.

Hydrochar from agricultural wastes is regarded as a prospective and low-cost material to activate peroxymonosulfate (PMS) for degrading pollutants. Herein, a novel in-situ N-doped hydrochar composite (RHCM4) was synthesized using montmorillonite and waste reed straw rich in nitrogen as pyrolysis catalyst and carbon source, respectively. The fabricated RHCM4 possessed excellent PMS activation performance for decomposing quinclorac (QC), a refractory herbicide, with a high removal efficiency of 100.0% and mineralization efficiency of 75.1%. The quenching experiments and electron spin resonance (ESR) detection disclosed free radicals (•OH, •SO 4 − , and •O 2 − ) and non-radicals ( 1 O 2 ) took part in the QC degradation process . Additionally, the catalytic mechanisms were analyzed in depth with the aid of various characterizations. Moreover, the QC degradation intermediates and pathways were clarified by density functional theory calculations and HPLC-MS. Importantly, phytotoxicity experiments showed that RHCM4/PMS could efficaciously mitigate the injury of QC to Solanaceae crops (pepper, tomato, and tobacco). These findings give a new idea for enhancing the catalytic activity of hydrochar from agricultural wastes and broaden its application in the field of agricultural environment.

Advanced oxidation processes (AOPs), based on sulfate radical (SO 4 ·- ) produced by peroxymonosulfate (PMS), can effectively mineralize refractory organic pollutants. However, the coexistence of anions and natural organic matters in actual wastewater prevents the application of AOPs. A simple one-step method was used to prepare FeS/Fe 3 O 4 co-modified biochar materials (FFB) that could activate PMS to degrade quinclorac (QNC) with a removal rate of 100%, even exhibiting optimum degradation of QNC reached 99.31% in irrigation water, demonstrating excellent anti-interference performance for co-existing anions and natural organic matter. Meanwhile, ecotoxicity analysis showed that the toxicity of degradation intermediates was lower than that of QNC. Characterization results demonstrated the even distribution of FeS and Fe 3 O 4 onto biochar, supplying abundant Fe 2+ to activate PMS producing reactive oxygen species (ROS), while the generated Fe 3+ after reactive continue to be reduced with sulfur species to promote the cycle of Fe 2+ /Fe 3+ . The coexistence of ·OH, SO 4 ·- , 1 O 2, and O 2 ·- in the FFB/PMS-QNC system suggest the possession of two pathway with free radical and non-free radical pathways to degrade QNC. The density functional theory (DFT) was used to analyze the adsorption sites and adsorption energy of PMS, as well as the differential charge density, which further proved the generation of SO 4 ·- , O 2 ·- and 1 O 2 . In addition, the electrochemical test results showed that electron transfer also played an important role in the degradation of QNC. This study provides a feasible approach for the removal of organic pollutants in actual water.

In this study, a highly specific and sensitive monoclonal antibody (mAb) against quinclorac (Qui) was prepared. Based on the selected mAb, 2G3, an indirect competitive enzyme-linked immunosorbent assay (ic-ELISA) and an immunochromatographic strip assay were established for the detection of Qui in actual samples. The 50%-inhibitory concentration of mAb 2G3 against Qui was 48.763 ng mL−1. No cross-reaction with other quinolines indicated that mAb 2G3 had high specificity. The recovery of the established ic-ELISA method was in the range of 85.6% to 98.9%. The cut-off value of Qui in cucumber and tomato by immunochromatographic strip was 200 ng g−1. The analysis results of ic-ELISA and immunochromatographic strip assay were consistent with the results of LC-MS/MS, which further proved that the established ic-ELISA and immunochromatographic strip assay could provide valuable tools for the rapid detection of Qui residues in cucumber and tomato samples.
