Abstract

Abstract: By using the parallel printing I/O port of PCmicrocomputer and the graph plotter port of MP-1 stripping analyzer, an interface circuit was designed for data acquisition. After the pretreatment of the polarographic signals, Kalman Filter was used in resolution of the overlapping polarographic waves of mixtures of in and Cd. The results showed that when the relative concentration of in and Cd was 1: 16 to 13: 1, the satisfactory quantitative results of two components can be obtained with this on-line microcomputer based Kalman Filter.Some parameters in the process of Kalman Filtering were discussed as well.

Key words: On-line Kalman Filter, Polarography, Indium and cadmium
