ABSTRACT
In this study, a simple, sensitive separation/preconcentration procedure is presented for the determination of copper, nickel and lead at trace levels by atomic absorption spectrometry. The procedure is based on chelate formation of the investigated metals with calmagite and recovery of the chelates from the Amberlite XAD-I 180 column with 0.5 M HNO3. The presented procedure wag applied to the preconcentration and separation of copper, nickel and lead in urine and haemodialysis concentrates with satisfactory results (recoveries in the range of 95-100%).
