摘要: A new versatile solid phase extraction and spectrophotometric determination of uranium (VI) was proposed with using poly(caprolactone-b-vinyl benzyl chloride-g-dimethyl amino ethyl methacrylate), poly(CL-b-VB-g-DMAEMA), amphiphilic brush type block/graft copolymer. The method is based on the adsorption uranium(VI)-pyrocatechol violet complex surface adsorbent. parameters such as pH, amount ligand copolymer, sample volume were optimized. Detection limit, preconcentration factor relative standard deviation found 0.45 µg L−1, 100 3.8 %, respectively. Adsorption capacity polymer for uranium(VI) 52 mg g−1. applied to different water samples reference materials.
