Free indium concentration determined with AGNES

Abstract: Indium is increasingly used in electronic devices, from which it can be mobilized towards environmental compartments. Speciation of In in waters is important for its direct ecotoxicological effects, as well as for the fate of this element in the environment (e.g. fluxes from or towards sediments). Free indium concentrations in the environment can be extremely low due to hydrolysis, especially important in trivalent cations, to precipitation and to complexation with different ligands. In this work, the free ind… Show more

“…Because AdSV requires the addition of a complexing agent, further speciation analyses are more involved. Very recently, the technique Absence of Gradients and Nernstian Equilibrium Stripping (AGNES), commonly used for free ions quantification of trace metal elements [23][24][25], has been extended to indium analysis with a sensitivity below nanomolar concentrations [26]. This equilibrium technique provides new perspectives for acquiring thermodynamic information pertaining to indium binding properties with molecular or colloidal ligands.…”

“…При этом зачастую не принимают в рассмотрение влияние ионной среды. Есть публикации [2,18,132], в которых вообще не учитывают К А индийсодержащих частиц в водной фазе и индия в фазе электрода (жидкой ртути) в широких диапазонах концентраций компонентов. Но ошибки опре-деляются не только этим обстоятельством.…”

“…Индий -стратегически важный редкий и рассеянный металл, и его химия и технология активно обсуждаются в литературе последних лет [1][2][3][4][5][6][7]. Знание химического состояния индия в растворах различного состава необходимо для решения широкого круга научных и прикладных задач, в том числе, для расчета равновесий, определения состава комплексов, образующихся при экстракции в органической фазе, для оптимизации условий получения материалов и т. п.…”
