Determination of Trace Selenium in Fish by Microwave Digestion-Hydride Generation-Atomic Fluorescence Spectrometry

Zang Su

Abstract

The amount of trace Se in fish was determined by microwave digestion-hydride generation-atomic fluorescence spectrometry.The sample was digested with HNO 3-H 2O 2.The hydride was generated in 3mol·L -1 HCl media with 2%(W/V)KBH 4 as a reducing agent.The experimental conditions of microwave digestion and prereduction were studied.This method is accurate and rapid,and used to the standard reference material with good agreement to the certified values.
