Simultaneous determination of trace amount of Fe、Al、Ca、Mg and Mn in Silicon metal by ICP-AES

WT5BZ]This paper provides a method for the determination of trace amount of Fe, Al, Ca, Mg, and Mn in silicon metal by inductively coupled plasma atomic emission spectrometry(ICP AES).The samples were dissolved by mitric acid,hydrofluoric acid and perchloric acid.Heat to dry,Add hydrochloric acid to dissolve and transfer the solution into flask.Dilute to mark with water.Determine the five elements at the selecting conditions.This method is rapid,simple and accuracy.The five elements can be determined simultaneously by means of selecting the multi element determining mold.The recoveries of five elements are between 93 9% and 103 9% and the relative standard deviation betweem 1.3% and 4.0%.
