COMPUTER-ASSISTED POLAROGRAPHY AND VOLTAMMETRY - APPLICATIONS TO KINETIC-STUDIES OF METAL COMPLEXATION

The computerized polarographic system described consists of commercially available components (Metrohm E506 polarograph, E608 controller and E612 scanner with an IBM AT-compatible personal computer) with suitable software for different polarographic methods. Instrument control and data evaluation are handled by the computer. The set-up provides a simple, inexpensive conversion of an analog instrument to a computer-controlled system. Computer-assisted polarography offers improved precision and accuracy in data processing as well as high data-collection rates (e.g., linear sweep and cyclic voltammetry). Studies of the kinetics of complexation of cadmium with EDTA by cyclic voltammetry are presented as an example.
