电感耦合等离子法测定环境积尘中铅的研究

用细毛刷清扫收集普通居民房顶积尘，参照土壤样品预处理方法-普通酸分解法处理样品，以国标样品、不确定度实验、加标回收实验为质控手段，探索采用电感耦合等离子法测定环境积尘中铅的含量。实验结果表明，该法能将积尘样品完全消解，且电感耦合等离子法测试方法性能稳定、快速、准确，优于其他方法。

Determination of Lead in Environmental Dust by ICP- MS

The dust on the roof of the residential building was collected with the fine brush. The samples were processed by the common acid decomposition method with reference of the soil sample pretreatment methods. With national standard samples, the uncertainty experiment and the recovery experiment as the quality control methods, the lead in the environmental dust was determined by ICP - MS. The experimental results showed that the sample could be completely digested, and the ICP - MS is a stable, rapid, accurate and superior method.
