dc.description.abstract A capillary gas chomatographic method has boar developed for the determination of vanadium from rock samples. It is based on complexation of analyte by bis (acetylpivalylmethane) ethylanediimine (H(2)APM(2)en) followed by solvent extraction, elution and reparation through capillary gas chromatographic column BP5 (50 m x 0.22 mm i.d) with layer thickness 0.25 mum The complexing reagent and copper (II), nickel (II), palladium (II) and platinum (II) as metal chelates of H(2)APM(2)en completely separated from oxovanadium (IV). However, high concentration of iron (II) supressed oxovanadium (IV) response. Quantitation was carried out using standard addition after acid dissolution of rock samples. The amount of vanadium was found within 101.5-687.5 mug/g with relative standard deviation (RSD) 2.05-4.27 %. en_US
