Abstract
Nine elements,Si,Mn,Ni,Al,Pb,Zn,Sn,Fe and Sb were simultaneously determined by ICP-AES.Samples were decomposed with HCl and H 2O 2 and analyzed at the same time under the best conditions.The method is fast and accurate,with the relative standard deviation less than 2% and recovery rate as 95%～105%.
A significance statement is not available in the OpenAlex record.
