Abstract
A new analytical method was proposed to simultaneously determine Cd,Co,Cu,Mg,Mn,Ni,Pb,Zn and Ca in laterite nickel ore by inductively coupled plasma atomic emission spectrometry(ICP-AES).The samples were first treated by hydrochloric acid,nitric acid and hydrofluoric acid and then determined by ICP-AES under optimal instrument conditions with hydrochloric acid as the testing medium.The detection limits for each element were 0.0001%～0.0033 μg/mL and the relative standard deviations(RSD,n=6)were 0.15%～1.89%.The recoveries for testing the spiked samples were between 91.4%～107.2%.The comparison test showed that the values determined by ICP-AES were consistent with those by flame atomic absorption spectrometry.
