Colorimetric copper (Ⅱ) ions detection in aqueous solution based on the system of 3′3′5′5′-tetramethylbenzidine and AgNPs in the presence of Na2S2O3
Herein, a colorimetric copper (Ⅱ) ion (Cu2+) detection system based on the oxidization reaction of 3′3′5′5′-tetramethylbenzidine (TMB) and Ag(S2O3)23− (in aqueous solution) was designed. The detection system comprised TMB, silver nanoparticles (AgNPs) and thiosulfate (S2O32−). It was observed that A...
