| Abstract: | Madaline neural network was used for the simultaneous determination of contents of Cu, Co and Ni using 4 _ (2 _ pyridylazo) _ resorcinol(PAR)-Cu, Co and Ni colour system in which the spectra of complexes of PAR with Cu, Co and Ni are seriously overlapped. The mean recoveries of Cu, Co and Ni are 94%, 101% and 102%, respectively. The network is better than other networks in training speed and accuracy, therefore, it is a prospective method for spectrophotometric analysis of multicomponent system. |
