Abstract:

A procedure is described for the inductively coupled plasma emission spectroscopic determination of Cd, Co, Cu, Fe, Mo, V, and Zn in <1 mL of serum after digestion in nitric and perchloric acids and preconcentration with a poly(dithiocarbamate) resin. Recoveries are 91 to 106%. The determination of As and Se in serum by hydride generation and ICP-AES is performed after the interference of Cu on Se hydride generation was reduced by complexation of the Cu with poly(acrylamidoxime) resin. Verification with NBS-SRMs as well as with human sera samples is reported.
