摘要
介绍了一种快速测定甲醇中碱金属和碱土金属离子含量的方法。该方法先对200mL的甲醇进行水浴蒸干,然后用水定容到50mL,用非抑制离子色谱法测定Na^+、K^+、Mg^2+、Ca^2+,外标法定量,方法简便。
In this method,200 ml of methanol was evaporated to dryness on a water bath,with water constant volume to 50 ml.Na^+,K^+,Mg^2+,Ca^2+ions were determined by non-suppressed ion chromatography and quantified by external standard method.
