抄録

Vanadium, chromium and molybdenum were determined by atomic absorption spectrometry with a coated graphite furnace. Pyrolytic graphite tubes were coated with boron carbide. A mixture of nitrates of nickel and strontium and boric acid was then added to a sample solution as a matrix modifier. Using this coated tube, the determinations of vanadium, chromium and molybdenum were successful with high sensitivity and better reproducibility. No interference from metal nitrates and chlorides with vanadium and molybdenum determinations and from metal nitrates with chromium determination was observed. The chloride interference with chromium and the sulfate interference with analyte could be removed by adding ammonium salt of EDTA.
