研究了原子吸收分光光度法测定氯酸钠厂母液中的金属元素钙、镁的含量。对最佳仪器条件进行研究,使被测元素的浓度与吸光度值呈线性关系,相关系数R不小0.999 0。 The atomic absorption spectrophotometry was used to determine the content of calcium and magnesium in mother liquor of sodium chlorate factory. The optimum instrument conditions were studied, the concentration of the measured element and the absorbance value was linear, the correlation coefficient R is not small 0.999 0.
