Simultaneous Species Determination in Industrial Solutions by Differential Alternative Pulse Voltammetry (DAPV)

The Differential Alternative Pulses Voltammetry (DAPV) combining the high sensitivity of the Differential Pulse Voltammetry with the increased resolution of the second order voltammetric techniques was applied for on-site simultaneous determination of species as As(III), Pb(II) and Tl(I) in industrial solution without preliminary species separation. The limits of the species concentration ratios allowing simultaneous determination with preset precision of les than 10% were determined. The method was applied for determination in real industrial solutions.
