NEW POSSIBILITIES IN VOLTAMMETRY - EXTRACTION INTO THE ELECTRODE BULK

Possibilities of applying extraction in the selective preconcentration of inorganic and organic substances at electrodes under voltammetric conditions are considered. The principles of making such electrodes an d the methods of preconcentration are discussed. Theoretical approache s to the use of liquid-liquid, liquid-solid, and liquid-membrane extra ctions in the preconcentration of analyte components into the electrod e bulk are analyzed. Examples of application and the outlook for resea rch in this field are considered.
