【摘要】 使用原子吸收火焰法对盐中的钙、镁离子含量测定进行探究,建立检测方法。采用水溶解盐,用镧盐作为Ca、Mg的释放剂以消除共存元素的干扰。在测镁元素时需要扣除背景吸收,用火焰原子吸收法测定盐产品中的Ca、Mg离子。结论分析结果表明,方法快速、简便、准确,各分析元素都得到比较理想的结果,可以用于测定盐中的钙、镁离子含量。更多还原

【Abstract】 Study the determination of calcium, magnesium ion content by atomic absorption flame method and establish a determination method. Using lanthanum salt s releasing agent of Ca, Mg a to eliminate the interference of coexisting elements. Using atomic absorption flame method to test Ca and Mg iron in salt product should deduct background absorption in the determination of magnesium. The conclusion show that this method is fast, easy and accurate; analysis of each element achieves ideal result and it is can be used in the determination of the iron content of Ca and Mg.更多还原
