摘要
采用电感耦合等离子发射光谱,测定离子膜烧碱法中二次盐水钙镁含量,准确度高,相对标准偏差0.57%～1.11%,本方法灵敏度、准确度高,重复性好。
Calcium-magnesium content in secondary brine from production of caustic soda by ion-exchange membrane process was detected by inductively coupled plasma emission spectroscopy.The results show that the method is good sensitivity,high accuracy and good repeatability,relative standard deviation is 0.57%~1.11%.
