DETERMINATION OF ARSENIC CONTENT IN LITHIUM COBALT OXIDE BY HYDRIDE GENERATION-ATOMIC FLUORESCENCE SPECTROMETRY

Shu Tang

Abstract

A method for the determination of arsenic in lithium cobalt oxide by hydride generation atomic fluorescence spectrometry is proposed.The conditions for sample digestion and hydride generation are optimized by the experiments.The detection limit of the method for arsenic is 0.05 mg/kg and recovery is 99.4%～105.5% with precision of 1.93%～8.02%(RSD,n=7).
