The ICP-AES method for simultaneously determined Mn, Al ,Fe,Cu,Ti and, P in nicked alloy was used instead of the atomic absorption spectrometry method ,by which the above mentions elements were determined individually ,optimizing the conditions of the ICP, the analytical lines for every element were determined ,Sample were decomposed with HNO3 and analyzed at the same time under the best condition .The method is fast and accurate with the relative standard deviation less than 3.2 % and recovery rate as 91.8 %- 102 %, The method is suitable for daily testing for trace elements in nicked alloy.
