✦ Synopsis

Optimal conditions for direct electrothermal atomic absorption (ET-AAS) determination of Al, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, and V in high purity bismuth oxide and tellurium oxide are described. Matrix interference on the atomization of the analytes is studied. The analytical method developed in this paper permits determination of 0.005 mg g 01 Cd and Mn; 0.02-0.05 mg g 01 Al, Cu, Cr, and Fe; 0.1 mg g 01 Co, Ni, and Pb; 0.5 mg g 01 V with relative standard deviation 3-8%.

In order to precisely determine trace amounts of carbon (below about 5 mg/g) and oxygen (below about 5 mg/g) in a high-purity iron, it is necessary to remove carbon and oxygen adsorbed and combined on the surface of the iron as contamination, and to lower the experimental blank value. When the surfa
