应用ICP-MS测定大气降尘中有毒重金属的化学形态

Identifying the Chemical Speciation of Toxic Heavy Metals in Dustfall Through ICP-MS

本文介绍根据“MeasurementandTestingProgramme”制定的四步萃取法对降尘样品进行预处理,然后采用ICP-MS法进行含量测定。研究了不同粒径降尘样品中有毒重金属元素Cu、Pb、Zn、Cr的形态分布特征。

This paper introduces the dustfall’s pre-dealing way based on the four-step extraction method made by “Measurement and Testing Programme”. The speciation distribution factor of toxic heavy metals Cu, Pb, Zn, Cr is identified in this research through ICP-MS.
