摘　　要：将AgCu28样品用硝酸溶解,用电感耦合等离子体原子发射光谱(ICP-AES)法直接测定AgCu28中的微量P含量。在仪器吹扫模式下,选择合适波长消除光谱干扰,用背景点扣除的方式消除基体干扰。P检测范围为0.0005%~0.02%,加标回收率为105.0%~109.5%,精密度(RSD)为4.45%。方法准确、快速、简便。AgCu28 sample is dissolved by nitric acid,the trace amount of P in AgCu28 is directly measured by ICP-AES method.Under the instrument purge mode,the suitable wave length is selected to eliminate the spectral interference,and the matrix interference is eliminated by background point deduction method The detection range of P is 0.0005%~0.02%,the adding standard recovery rate is 105.0%~109.5%,the precision degree(RSD)is 4.45%.The method is accurate,rapid and simple.
