- 論文の詳細を見る
The analytical applicatians of salicyloylhydrazones of di-2-pyridyl ketone (SHDPK) and 2-benzoylpyridine (SHBP) are described. A rapid, sensitive atomic absorption spectrophotometric method for the determination of trace amounts of Pb(II) is presented. Both reagents form stable cationic complexes with lead. These complexes are quantitatively extracted into isobutyl methyl ketone (IBMK) in the presence of perchlarate as ion-pair. The lead-SHDPK complex formed in an acid medium (pH=4.5) has been used for the determination of lead in water samples.
