Abstract
The synthesis, characteristics and analytical applications of pyridine-2-acetaldehyde salicyloylhydrazone (PASH) are described. The reagent reacts with vanadium(V) to produce a yellow 1 : 1 complex (λmax.= 415 nm, ε= 1.87 × 104 l mol–1 cm–1 in chloroform). The yellow complex, extracted into chloroform, has been used for the spectrophotometric determination of vanadium in a steel, a lead-vanadium concentrate and a phosphoric acid sample. A procedure based on the standard additions method has been applied satisfactorily to the determination of trace amounts of vanadium at the parts per billion level (parts per 109).Keywords
