Abstract:

The computer optimization of anodic stripping voltammetry ASV measurements has been investigated. The approach taken has been to specify desired performance criteria then, using a suitable theoretical model, the on-line computer makes initial measurements, imposing subsequently the values of the various experimental parameters required to achieve the desired response. In this study, the authors have chosen to optimize signal-to-noise and signal-to-background ratios for linear sweep ASV, studying metal ion solutions in the range 1 x 10 to the -5th power M to 1 x 10 to the -8th power M. An interactive approach to peak location and current measurement has been used, allowing optimized analysis of multicomponent solutions to be performed with a minimum of sophisticated programming algorithms. By careful selection of values for the performance criteria, an automated analysis may be performed satisfactorily over a wide range of concentrations.
