Abstract
An analysis method for the simultaneous determination of Mn, Ni, Al, Pb, Sn, Zn and Fe in aluminum brass by ICP - AES has been put forward, in which the optimum spectrum line and suitable working conditions of spectrometer for determination of each element were chosen, the relative standard deviation (RSD) was <2% and the recoveries were in the range of 95% ~105%. There-suits demonstrated that the analytical error and the precision for the determination of Mn, Ni, Al, Pb, Sn, Zn and Fe were in accord with the requirements of the National Standards GB/T5122. Moreover, the precision and recoveries were satisfactory and the method was rapid and simple.关键词
