Preparation and Characterization of Broad-Spectrum Artificial Antibody for OPPs Based on Dummy Template Imprinting Technique

A molecularly imprinted polymer was prepared using diethylphosphonoacetic acid (DPA) as a dummy template for use as an artificial receptor for organophosphrous pesticides (OPPs). Scanning electron microscopy (SEM) was employed to observe the morphology of the prepared polymer. Ultraviolet spectroscopy and 1H NMR analysis reveal that DPA and the monomer integrate by hydrogen bonding with a molar ratio of 1:2. A static adsorption experiment, Scatchard analysis, and dynamic adsorption and selective binding tests demonstrated that the obtained polymer can effectively bind a group of OPPs containing dimethoxyl or diethyoxyl.
