Abstract
A novel sensor was fabricated for simultaneous quantification of tin and lead. The sensor is based on the adsorptive accumulation of tin and lead onto an amino-functionalized superparamagnetic iron oxide nanoparticle (spion)/glassy carbon electrode. Main parameters affecting the stripping performance mainly, accumulation potential, pH, accumulation time and interference by other ions were studied. The detection limits were found to be 0.12 and 0.10 ng/mL at an accumulation time of 100 s for lead and tin, respectively. The proposed procedure was validated using a standard procedure. The sensor is applied to analysis of tin and lead in water samples.
