Determination of Metal Elements in Electrolytic Manganese Metal by ICP-AES

10 metal elements such as Ca,Mg,Fe,Cu,Co,Ni,Zn,Cr,Sb and Pb in electrolytic manganese metal were determined by inductively coupled plasma-atomic emission spectrometry(ICP-AES).The sample was dissolved in HNO3 and HCl by microwave digestion then the above 10 metal elements in the solution was analyzed directly by ICP-AES.The analytical line,matrix effects and plasma parameters were discussed.The optimum conditions for the determination were tested and discussed.The result indicated that each of the 10 metal elements was limited between 0.004—0.053μg/mL and the relative standard deviation(RSD) was less than 3.5% and the recovery of the samples was in the range of 93.7%—105.1%.
