A simple method for voltammetric determination of trace amounts of selenium in diverse matrices

La determinación de cantidades traza de Se en aguas industriasles y en tabletas de vitaminas es posible mediante un método muy simple de voltamperometría basado en el diferencial de impulsos de reducción polarográfica de Se (IV).

"A simple and convenient method is described for the determination of low concentration selenium in samples of industrial waste and vitamin tablet. The method is based on the differential pulse polarographic reduction of Se (IV) in presence of alanine in ammonium chloride medium. Linearity of the calibration curve was achieved upto 44ppm with a limit of determination of 5 μg/L. Major metal ions copper, lead and zinc did not interfere."
