摘要
采用离子色谱法同时测定白云石中高含量钙镁 ,该法与目前使用的络合滴定法相比 ,具有准确可靠、操作简便快速、无干扰等特点。对样品测定取得了满意的结果 ,氧化钙与氧化镁的含量分别为 3 1 .99%和 2 1 .4 7% ,相对标准偏差分别为 0 .81 %和 0 .65% ,平均回收率分别为 99.9%和 1 0 2 %。
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.
