ICP-MS法对镍冶炼企业粉尘中主要金属含量检测分析

Objective To establish the use of inductively coupled plasma mass spectrometry ( ICP-MS ) analysis of nickel in each production link dust multi element analysis method and the analysis of nickel and other five kinds of metal content Method The optimal detection condition was optimized and 6 metal elements (Ni, Mn, Cu, Cd, Pb, Sb) in nickel powder were simultaneously detected. Result The contents of Nickel in occupational dusts from Ore-Dressing Workshop、Copper-Nickel Separationg Workshop、Smelting Workshop and Refining Workshop are 81.12%、48.26%、77.40%和99.98%；The precision and accuracy of the method is excellent and percent recovery was 90.8%-106.3%. Conclusion The method is accurate, rapid, and can be simultaneously used for nickel production occupation exposure to dust in a variety of metal elements determination, with satisfactory results. Nickel production process for heavy metal composition was significantly affected by the production, production of different heavy metal occupation exposure is considered one of the important factors.
