Selective, Simple and Economical Method for the Voltammetric Determination of Bi(III) in the presence Cystine in Non – Complexing Solution

The simple and fast method for the determination of Bi(III) in non-complexing solution was proposed. The catalytic activity of cystine on Bi(III) ions electroreduction process were utilized. The calibration graph of Bi(III) in 4 mol·dm−3 chlorate (VII) in the presence of 1·10−2 mol·dm−3 cystine is l...

Description
Summary:The simple and fast method for the determination of Bi(III) in non-complexing solution was proposed. The catalytic activity of cystine on Bi(III) ions electroreduction process were utilized. The calibration graph of Bi(III) in 4 mol·dm−3 chlorate (VII) in the presence of 1·10−2 mol·dm−3 cystine is linear in the range of concentrations of Bi(III) from 7·10−7 to 4·10−5 mol·dm−3. The detection and quantification limits were found to be 1.2·10−7 mol·dm−3 and 4.02·10−7 mol·dm−3, respectively. Precision and recovery of the method were investigated by determination of Bi(III).
