Abstract
This paper describes the investigation of surface modified CdTe/ZnS nanoparticle as a sensing receptor for Hg2+ ion detection by optical approach. Glutathione-modified CdTe/ZnS nanoparticles were used as a fluorescence sensor for Hg ion which involved in the fluorescence quenching. The experiment results show that fluorescence intensity is the highest when the mol ratio of CdTe and ZnS is 1:2 in nanoparticle structure, and the fluorescence intensity of nanoparticle depends linearly on mercury ion concentration, and the correlation coefficient R = 0.9823, and simulation error less than four percent. This technique demonstrated an effective detection of mercury in aquatic environment.
