The advances in electrochemical determination of gallium (III)

Abstract

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.

Using a Simple Magnetic Adsorbent for the Preconcentration and Determination of Ga(III) and In(III) by Electrothermal Atomic Absorption Spectrometry

“…These latter techniques are expensive, mainly due to the high argon consumption. This fact, together with interferences caused by overlapping spectral lines in ICP-OES or the high salt content of some samples, which is incompatible with ICP-MS, has led several authors to propose electrochemical methods, mainly based on anodic stripping voltammetry, that achieve similar detection limits [ 38 , 39 , 40 , 41 , 42 ].…”
