Indirect Determination of Vanadium by Atomic Absorption Spectrometry

Determination of germanium, vanadium, and titanium by carbon furnace atomic absorption spectrometry

“…Vanadium was determined by flame AAS after extraction into methyl isobutyl ketone as a complex with cupferron (15). Vanadium was indirectly determined as vanadium molybdophosphoric acid by flame AAS (16). The nature of the interference of nitric acid in the determination of vanadium by flameless AAS was described (17).…”

“…The Kniseley burner has been used for the determination of vanadium ( 423). An indirect method for the determination of vanadium involves the formation and extraction of molybdovanadophosphate and the subsequent determination of vanadium (280). Specific applications include the determination of vanadium in the presence of large amounts of iron (263), in nickel base alloys (677), in iron ores and slags (369), in calcium sulfate (262), in ores (211), in silicates (370), and in silicates following the extraction of the vanadium-cupferron complex into butyl acetate (491).…”

“…Ferroin was used to detect the end point in the determination of chromium in tanning solutions (586), and leather ash (587), while phenylanthranilic acid was used for chromium in Fluorometric-morin: study of conditions (508) Atomic absorption spectrometry: study of conditions (575), La (184) Fluorometric-quercetin: Zr (89) Atomic absorption spectrophotometry: study of sensitivities (527); study of flame (423,456); indirect method (280); Fe (263); Ni (677);…”
