A method for determination of impurity elements in nickel lanthanum alloy by inductively coupled plasma atomic emission spectrometry (ICP-AES )was proposed. All the influencing factors on spectrum measuring were investigated.The sample was decomposed by mixed acid(HCL ,HNO3 ) ,the ex-periment of instrument parameters ,selection of analysis lines were studied ,the optimal determination conditions of instrument were obtained ,the analytical lines were Si 251.611 nm ,Mn 257.610 nm ,Mg 285.213 nm ,Cu 324.752 nm ,Zn 213.857 nm ,Cd 214.440 nm ,Pb 220.353 nm ,Zr 343.823 nm ,respec-tively ,the effect of matrix and coexist elements on the determination was carried out. The matrix effect was corrected by matrix matching. The detection limits were 0.0003-0.015 μg/ml ,the recovery rates were from 80% to 108% ,the RSD were less than 8% .
