“…Ga(III) is reduced to Ga(0) in different supporting electrolytes (Table 1) [10][11][12][13][14][15][16][17][18][19][20]. In numerous media it is reduced or oxidized irreversibly [15,16,21].…”

“…However, these techniques have relatively low sensitivity (n•10 -5 M). Other articles [16,18,[23][24][25][26] have reported the use of anodic stripping voltammetry (ASV) for Ga(III) determination in thiocyanate solution. Pulse modes of ASV, which include phase-selective anodic stripping voltammetry (PSASV), square-wave anodic stripping voltammetry (SW ASV) and differential pulse anodic stripping voltammetry (DP ASV), reduce the residual charging current, and consequently lower concentrations of Ga(III) (10 -9 -10 -7 M) can be detected.…”

“…The most common type of interference is the similarity of peak potentials [17]. From this point of view Zn(II) and As(III) have been recognized as potential interferents [14][15][16]18,29]. In some cases Ga(III) needs to be separated from Mo, Mn, Sn, Ni, Co, and U [14,15,18,29].…”

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.

“…and fluorimetry (8,9) involve separation of interfering ions. Electrochemical techniques are reported to be good and sensitive for the determination of Ga at the 10 µg/mL level (10). Laser-induced breakdown spectroscopy has also been used for the determination of Ga in liquid matrices (11).…”

Energy dispersive X-ray fluorescence (EDXRF)-based methods were developed for the determination of gallium (Ga) in aqueous solution using a set of standard solutions in the concentration range of 20-5000 µg/mL. When these methods were applied to the determination of Ga in U-containing solutions, the estimated values were found to be lower due to matrix effects. Hence, they were modified using another set of Ga standards containing U concentrations at 100 mg/mL. The modified method was found to be applicable for the estimation of Ga from 50 µg/mL to 5 mg/mL (i.e., 0.005% to 0.5% Ga in U). Synthetic samples were analyzed by these methods in order to evaluate their reliability and reproducibility. Another method was also developed for the direct determination of Ga in (U-Ga) mixed oxide powders in the concentration range of 0.02 to 50 mg/g. The developed methods will be especially useful for the fast routine determination of Ga in U-Ga alloys.

“…They are used for the study of nuclear materials [21], performance of zirconium at elevated temperature and pressure [22], behavior of stainless steel in PWR primary coolant conditions [23], and for the prediction of UO2 nuclear fuel dissolution rate under waste disposal conditions. Application of electroanalytical techniques for the determination of nuclear materials can also provide an interesting alternative over the traditional spectroscopic methods [24]. Electrochemical techniques offer several advantages over spectroscopic techniques.…”
