Abstract
Two types of HgO-modified electrodes are disclosed. The HgO-modified electrode according to the present invention comprises, HgO particles as precursor of mercury, which can be exposed on the surface of the said electrode and then can be reduced electrochemically into micro-droplets of mercury; and electro-conductive material to maintain optimal conductivity of the said modified electrode. In the HgO-modified electrode according to the present invention, built-in mercury precursor, HgO can be utilized feasibly for the generation of the surface mercury droplets by in situ electrochemical treatment or pretreatment without necessity of Hg.sup.2+ solution. The electrode surface can be renewed easily either by a simple polishing process for the bulk-modified electrode type-I or by simple exchange for the screen-printed disposable type modified electrode type-II. So further simplification of anodic stripping analysis process is possible by employing the HgO-modified electrodes according to the present invention.
