✦ Synopsis

An expert system for the voltammetnc deternunatlon of Cu, Zn, Cd, Pb and In was developed The system guides the user m the choice of sample treatment, the most appropriate voltammetric procedure and the ldentlficatlon and determination of the trace metals The techniques implemented are differential-pulse polarography and anodlc strippmg voltammetry, using mercury drop electrodes Only well known methods are recommended, Hrlth particular attention to standard methods For the ldentlflcatlon and resolution of overlapping peaks (Cd and In), the system may call two external programs, written m turbo BASIC Quantification 1s carried out by means of the multiple standard addition method, and the quality of the cahbratlon graph IS tested by several statlstlcal validation tests The tool kit for the development of the expert system KES (Knowledge Engmeermg System) IS used Only commercially available material was used The system 1s easily portable If the shell for the development of the expert system IS employed
