| Abstract: | A new method for simultaneous specttophtometric determination of composition in multicomponent system has been developed.In this method,a FCA-PLS calibration model is obtained from known composition in multicomponent,system,and is then used to predict the concentrations of unkaows.A demonstration,coloured systems of cobalt,nickel, copper and zinc with 2-(5-bromo-2-pyridylazo)-5-diethylamino phenol in the buffer solu- tions of different pH,is given,and the results of quantitative determination are satisfactory. |
