摘要: A multi-functional hybrid of cellulose acetate with cadmium sulfide and Methylene blue (CA/CdS/MB) in a bead composition was synthesized investigated as photosensor-adsorbent for the rapid, selective, sensitive detection, adsorption Cu(II) ions. These CA-modified beads are composed multiple active sites possess surface area 58 cm2 g−1. They an efficient adsorbent maximum capacity 0.57 mg g−1. Photoelectrochemical (PEC) detection accomplished by modifying on glassy carbon electrode. The containing 20 mmol sulfur displayed widest linear analytical range (0.1–290 nM) lowest limit (16.9 nM) high selectivity reliable reproducibility. successful application has provided new insight selection responsive photoactive material PEC assay, well effective
