Abstract

An Hg(II) solid state electrode (ISE) was fabricated using HgS and the sparingly soluble sulfur salts of Cu and Ag, and the highest sensitivity of the ISE was obtained with 10% HgS (w/w) composition. The ISE shows a slope of about 29 mV towards the Hg (II) ion (pHg 1,0-7,0 mol L-1). Hg-SE has a response time of 20 s and a linear slope between pH 1.0 and 5.0. Its lifetimes are 1 year. It was determined that ISE is not sensitive to other ions. The LOD value of the electrode was measureted as 5x 10-8 M. In addition, after the validation of the electrode, Hg measurements in seafood were carried out.
