Removal of U(VI) from aqueous solution using AO-artificial zeolite

Amidoxime (AO) based adsorbents have been proposed as low cost and efficient adsorbent for U(VI). Herein, we present a simple strategy for preparing AO modified artificial zeolite. The composition and morphology of the materials have been confirmed via XRD, FT-IR, TGA and SEM. The AO-artificial zeolite was synthesised as an efficient adsorbent for adsorbing U(VI). The critical factors affecting U(VI) adsorption from aqueous solution were exploited, such as pH, contact time, temperature and adsorbent dosage. This study reveals AO-artificial zeolite, along with a low-cost, environmentally friendly and facile synthesis, can be regarded as a promising material for uranium-containing wastewater treatment.
