摘要
采用氢化物发生-原子荧光光谱法测定钴酸锂中砷。对样品前处理和氢化物发生条件进行了选择和优化。方法对砷的检出限为0．05mg／kg。方法的精密度（RSD，n=7）为1．93％～8．02％，回收率为99．4％～105．5％。
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）.
