Determination of Some Heavy Metals in the Dead Sea

Abstract

Abstract Chemical interferences in determination of trace heavy metals in a concentrated salt matrix like the Dead Sea and the ways to overcome them, is the object of this paper. Three different methods were checked for this matter. APDC-TCTFE extraction with GFAAS, direct determination by AAS with matrix modifier and Zeeman background correction and anodic stripping at the level of ng/mL. Chemical blank and recovery studies were performed concerning each method.
