The advances in electrochemical determination of gallium (III)

Electrochemical methods of gallium determination are reviewed. Voltammetric methods are the most widely used and a review of conventional supporting electrolytes and organic reagents available for gallium determination by voltammetry is presented. Several works dealing with gallium ion-selective electrodes have been reported, but only one of them was devoted to a coulometric technique of gallium determination. The electrochemical methods present several advantages over other methods and gallium can be determined in a variety of media such as water, food, soil, rocks, ores, and industrial objects.
