摘要
为了测定泥页岩中可溶性钙、镁离子的含量,采用了传统的钙、镁离子含量测定方法,但由于其他离子的干扰使测定终点难以观察。因此实验研究了采用CMP混合指示剂法测定钙,以K-B混合指示剂法测定镁的方法。实验结果表明改进方法对钙、镁检测的结果比传统方法准确度和精密度高。
In order to determine the content of soluble Ca and Mg ion in mud shale,we adapted the conventional measurement of determining the content of Ca and Mg ion. It is hard to ascertain the end point because of the interruption of other ion. So the CMP mixed indicator and K-B mixed indicator in determining the content of Ca and Mg ion were studied. The results show those two mixed indicator can improve the precision and accuracy of measurement.
