In situ modified electrodes in stripping voltammetry
Abstract
The application of three types of in situ modified electrode in stripping voltammetry is considered. Electrodes of type I were obtained by surface modification using triphenylmethane dyes and were used for the determination of the concentrations of SbIII and lā ions. Electrodes of type II were modified by electrodeposition of mercury on a graphite electrode and adsorption of Hgl3ā ions and were used in the cathodic stripping voltammetry of arsenic and tellurium. Electrodes of type III were modified with adatoms of thallium on a graphite electrode surface.
