摘要
基于国标原子吸收光度法测定铜钙元素，在锶镧元素共存下，尝试了钨精矿中铜钙元素的连续测定方法。结果显示，铜的质量分数0—10mg／L，钙的质量分数为0～15mg/mL符合比尔定律。加标回收率铜为99％-101％，钙为96％-103％。
Under lanthanum and strontium elements coexistence, continuous determination method of copper and calaium in tungsten concentrate is tested according to the national standard determination method of copper and calcium by AAS. The result shows that copper mass fraction is 0 - 10 mg/L,calcium mass fraction is 0 - 15 mg/L,bear＇s law is obeyed,the recovery of standard addition of copper and calcium are respecively 99% - 101% and 96% - 103%.
