摘要
建立了使用电感耦合等离子质谱法测定轻烧镁中铅、镉、砷、汞的方法,对测试条件和影响因素进行了探讨。实验表明,该法快速准确,测试检出限8 ng/L-220ng/L,回收率98.4%-110.1%。
A method for determining the contents of 4 heavy metal elements in the calcined magnesite including lead, cadmium, arsenic and mercury was established by using Microwave Degestion-ICP-MS. The optimized conditions and influence factors were discussed. The results showed that the proposed method has good precision and accuracy, the detection limits were from 8 ng/L -220ng/L, and the recoveries were from 98.4% to 110.1%.
