摘要
在ＨＣｌ介质中利用高含量的钠离子和硫酸根离子对镁的干扰效应及流动注入试样对镁的稀释效应，可对低含量的钙和高含量的镁用原子吸收法直接测定。方法简便，其分析速度为８０个样／ｈ。用于光卤石中钙、镁测定。
Direct determination of Ca 2+ and Mg 2+ in carnallite by atomic absorption can be carried out using the disturbing effct of Na + and SO 2- 4 on Mg and the dilution effect of sample flow injection on Mg. This process, with a analytical rate of 80 samples/h, is simple and convenient and has been used in the determination of Ca 2+ and Mg 2+ in carnallite. The results obtained are in agreement with ones obtained by complexmetric titration.
