| Abstract: | A method for the simultaneous determination of Zn2+? Pb2+? Fe2+? Mg2+? Mn2+? Cd2+andCa2+ by non- suppressed ion chromatography was developed. A mixture of 0. 5mmol / L ethylendiamine and 2mmol / L citric acid was used as mobile phase with a flow rate of 1.0ml/ min, Shim-park IC-Cl column was used with a conductivity detector.The dependences of capacity factor on concentrations of ethylendiamine and citric acid as well as on the pH value were investigated.This method was applied to the analysis of water. |
