| Abstract: | Comparing with complexometry,the ion chromatography is correct,reliable,simple,rapid and no interference,which was applied to simultaneous determination of Ca and Mg in dolomite with satisfactery results.Contents of CaO\-2 and MgO\-2 were 31.99% and 21.47%;its relative standard deviation were 0.81%and 0.65%;average recorery ratio were 99.9% and 102%,respectively. |
