✦ Synopsis

An expert system for the voltammetnc detemunatlon of Cu, Zn, Cd, Pb, In, NI, Co and Tl was developed unth special attention to methods for determmmg NI, Co and Tl at different concentration ratios The system guides the user m the choice of sample treatment, the most appropnate voltammetnc procedure and the IdenMicatlon and determmatlon of trace metals The techniques implemented are dtierentml-pulse polarography, anod~c stnppmg voltammetry and adsorptive stnppmg voltammetry, using mercury drop electrodes Only well known methods are recommended, with particular attention to standard methods For the ldentdicatlon and resolution of overlapping peaks, the system may be used m conJunction wrath two external programs, wntten m turbo BASIC Quantticafion 1s camed out by means of the multiple standard addition method, and the quahty of the calibration graph IS tested by several statistical tests performed by another external program The expert system IS developed using KES (Knowledge Engmeenng System)
