Determination of Selenium in Feed by Hydride Generation-Atomic Fluorescence Spectrometry

Deng Xiang

Abstract

The amount of Se in feed was determined by hydride generation-atomic fluorescence spectrometry.The sample was digested with acid.The hydride was generated in 6mol/L HCl solution with 0.8%(W/V) KBH_4 as a reducing agent.The method is sensitive and reproducibleility with satisfactory results.The detection limit is 1.75×10 -4 mg/kg with.Tthe recovery of 98.4%— 101.4%.
