| Abstract: | A simultaneous spectrophotometric method for the determination of Ca(Ⅱ) and Mg(Ⅱ)in mixture at pH 10. 5 is proposed on the basis of a study on a ACBK comple system. A lin-ear regression technigue is applied to the analysis of the multicomponent spectrophotometricdate at selected wavelengths |
