Detremination of Ten Trace Elements in Copper Sulfate by ICP-AES With Separating Matrix Deposited

Peng Yi

Abstract

The matrix copper was deposited and separated by ammonium sulfocyanate in solution with heating and 10 trace elements As,Cd,Co,Cr,Fe,Mg,Mn,Ni,Pb and Zn in Copper Sulfate were simultaneously determined by ICP-AES. The detection limits are 0.001—0.11μg/mL. This method was accurate, rapid and convenient. The recoveries are in the range of 88.6% (100.9%. RSD are less than 2%. It was used in the determination of Copper Sulfate with satisfactory results.
