摘　　要：铜铟镓硒靶材样品采用硝酸-盐酸(3+1)混合液低温电热板消解,采用电感耦合等离子体原子发射光谱法测定样品溶液中镓的含量。镓、钇的分析谱线分别为417.2,371.0nm,以钇为内标物。镓的线性范围在100mg·L^(-1)以内,方法的检出限(3s)为0.14mg·L^(-1)。方法用于铜铟镓硒靶材样品的分析,加标回收率为97.5%~104%,测定值的相对标准偏差(n=11)为0.31%~1.8%。The sample of CIGS target was digested by the mixture of nitric acid and hydrochloric acid（3＋1）with low temperature electricity plate.Amount of gallium in the sample solution was determined by ICP-AES.Analytical spectral lines of 417.2,371.0nm were chosen for the determination of gallium and yttrium respectively.Yttrium was used as internal standard.Linearity range of gallium was found within 100 mg·L^（-1） with detection limit（3s）of 0.14mg·L^（-1）.The proposed method was applied to the analysis of samples of CIGS target,giving values of recovery and RSD′s（n=11）in the ranges of 97.5%-104% and 0.31%-1.8% respectively.
