Disulfide based receptor was prepared using single step condensation reaction and suspended into organic nanoparticles to extend its practical application in aqueous samples. The prepared nanoparticles were used for the simultaneous recognition of three different metallic species (Cu 2+ , Cd 2+ , and Pb 2+ ) in aqueous media through voltammetric studies. These metals can be determined simultaneously and without interferences from any of the other potential interferent metal ions, as different signals are displayed in cyclic as well as differential pulse voltammograms, with a detection limit of 193.0 nM for Cu 2+ , 52.0 nM for Cd 2+ and 32.0 nM for Pb 2+ . The study was extended to real sample analysis by preparing the artificial mixtures of said metal ions.
