Abstract
In this research, we constructed chemical sensor for determining mercury in contaminated water because we needed fast, simple, low-cost, and accurate determination of mercury in different environmental systems. The constructed membrane composed of polyvinyl chloride PVC as a matrix material, 1, 5-diphenylthiocarbazone (dithizone) as electroactive compound, and di-n-butyl phthalate (DBPH) as a plasticizer. The optimum membrane composition 30% PVC, 65% DBPH, 5% dithizone exhibited the better Nernstian response. The results showed that probe is high stability along the pH range from (3.5 to 8). The electrode displays a linear log [Hg 2+ ] versus Electromotive force (EMF) response over a wide concentration range of (5?10 −6 to 1?10 −2 M) with Nernstian slope of 29.7?0.5 mV decade-1 and limit of detection 3?10 −6 M. The proposed sensor shows relatively high selectivity for mercury ion in different matrix solution, other ions had negligible interference effect on the reading. Keywords: Ion selective electrodes, Polymeric membranes, Determination of Mercury.
