摘要
将食盐配成饱和溶液 ,通过树脂分离富集 ,在盐酸介质中用火焰原子吸收光谱法测定其钙、镁含量。相对标准偏差1 8%～ 2 9% ,加标回收率 95 %～ 10 7%。
By making the salt into saturated solution and through the exchange resin calcium and magnesium will be enriched in the medium of hydrochloric acid. Thus the micro amounts of calcium and magnesium can be easily determined by FAAS. The recovery of the method is 95%-107%.RSD is 1 8%-2 9%
