Lower limits of detection for atomic absorption spectroscopy with direct aspiration of aqueous samples are commonly in the range o.og-I.0 p.p.m.1. These have been reported for iron and nickel as 0.05 p.p.m. by BARRAS". The purpose of the present study was a systematic attempt to lower considerably t
Several methods for the determination of vanadium are available, including spectrophotometric, spectrographic and polarograpllic techniques. Early atomic absorption methodsl-3 were not sensitive. Application of the nitrous oxide-acetylene flame" and of complexing agents" provided better sensitiviti
