A DEVICE FOR THE QUANTIFICATION OF MERCURY IN QEOUS 1/4/ NON_AQEOUS AND BIOLOGICAL SAMPLES AND A PROCESS THEREOF

摘要

In the present invention the basic principle of anodic stripping voltammetry with three electrodes configuration has been used to provide a novel electrochemical device and process for the quantification of low ppb (�g/l) level of mercury in aqueous/ non-aqueous & biological samples. In the present invention the three electrodes configuration essentially consists of a metal or carbon tipped sensing electrode, an inert metal counter/auxiliary electrode and a conventional reference electrode. The inventive step of the novel device of the present invention resides in the rotating sensing electrode constructed by embedding noble metal or carbon paste or graphite/glassy carbon circular/triangular/elliptical thin plate or rod at the side surface or bottom of the hollow cylinder made up of inert material and aqueous or non-aqueous electrolytic solution, which is either acidic 0.01N to 1N or neutral electrolyte of soluble salts 0.01M to
