| 摘 要： | 应用离子色谱法分析钻井液中阴阳离子的含量,关键在于钻井液的预处理。实验中,采用离心法去除钻井液中的固体颗粒,通过微孔虑膜过滤及活性炭吸附有机成分,可以有效地消除对测定的影响和对色谱柱的污染。实验结果表明,该方法具有良好的精度,其加标平均回收率为95%~105%,相对标准偏差优于4.0%。该方法用于实际样品分析,所得结果令人满意。

| Abstract: | The concentrations of anion and cation in drilling fluid of oil field were analyzed by ion chromatography. The key step in the analysis is the pretreatment of samples to eliminate interference on analysis and pollution on column. Solid particles in drilling fluid are removed by centrifuge, and the organic components are filtered by millipore filtering membrance. The method is accurate with the average recovery of standard addition between 95 % - 105 % and the RSD better than 4.0 %. The test results of pratical samples are satisfactory. |
