Abstract：Samples were dissolved using nitric acid, perchloride acid and hydrofluoride acid in the medium of 0.025 mol·L-1 EDTA with a kind of standard solutions, and the element contents of Ni, Cu, V, Mn, W, Mo, Co and Cr were determined by ICP-AES method. After investigating the spectral interfere from matrix element and coexistent elements, optimum spectral lines were selected for each analyzed element, and the analytical precision, detection limits and recoveries were measured. The results show that the detection limits of the method are very low, relative standard deviations (n=10) are less than 1%, and the recoveries range from 98.2% to 101.6%. The proposed method is accurate, reliable, simple, and rapid. The method satisfies.
