摘要：

A method for selecting optimum: wavelengths (OWL) in multicomponent spectrophotometric determinations has been developed. The algorithm and criteria proposed allow selection of OWL, the value of which is equal to the component number. The method was applied to the Al3(+)-Ox, Fe3(+)-Ox and TiO2+-H2O2-Ox (where Ox is 8-hydroxyquinoline) chemical systems. About 5% relative prediction error was obtained for concentrations from 0.009 to 0.036 mmol dm(-3).
