Simultaneous Determination of Indium and Thallium Ions by Anodic Stripping Voltammetry Using Antimony Film Electrode
An antimony film electrode (SbFE) was employed for the simultaneous determination of trace level of indium (In3+) and thallium (Tl+) ions in non-deaerated aqueous solutions by square-wave anodic stripping voltammetry (SWASV). The SbFE yielded well-defined and separated stripping peaks for these ions with low background contribution, after a short deposition time. Several key factors affecting the response signal of In3+ and Tl+ ions such as pH of the supporting electrolyte, deposition potential, and deposition time have been optimized. The lower detection limits obtained for Tl+ and In3+ ions were 2 and 8 μg/L, respectively. A good reproducibility with relative standard deviation of 3.8% and 2.8% for 70 μg/L Tl+ and In3+ ions was obtained (n = 10). The SbFE displayed linear calibrations in the concentration range from 20 to 100 μg/L In3+ and Tl+ ions. The proposed method was successfully applied to the analysis of In3+ and Tl+ ions in river water and tap water.
