Determination of Fe, Cu, Mg, Zn and Ti in High Pure Aluminum by ICP-AES

The method for the determination of Fe,Cu,Mg,Zn and Ti in high pure aluminum by ICP-AES was established.The spectral interferences from matrix elements and coexistence elements and the effects of hydrochloric acid dosage on analysis results were investigated.The analytical lines were selected and the detection limits of the method were determined.It was found that this method is fast,accurate and convenient.It was proved that using Fe 259.940 nm,Cu 327.396 nm,Mg 279.079 nm,Zn 213.856 nm,and Ti 334.941 nm spectral lines,Fe,Cu,Mg,Zn,Ti elements in high pure aluminumin the concentration range from 0.001% to 0.01% can be measured accurately and reliably by matrix matching method.
