Determination of Trace Selenium in Copper Ore, Lead Ore and Zinc Ore by Hydride Generation-Atomic Fluorescence Spectrometry with Baking Separation
详细信息   
摘要

The sample was digested using the semi-melting method with Aiskaer reagents (sodium carbonate and zinc oxide) and extracted by boiling water which separated Selenium from the main metal elements including Cu, Pb, Zn, other transition metals and precious metals. Meanwhile, other interference elements remaining in the solution are sheltered by adding molisite. A method for determining trace Selenium in copper ore, lead ore and zinc ore by hydride generation-atomic fluorescence spectrometry has the advantages of low interference and high sensitivity. This method was used to conduct experiments in seven lab.s from different areas using national standard materials with a precision repeatability limit, good reproducibility limit and high accuracy. The method can be applied to determine trace Se in soil and multimetallic minerals.
