Abstract

2-(5- bromo-2- oxoindolin-3-ylidenehydrazine carbothioamide), [5-Bromoisatin thiosemicarbazone (HBITSC)] extracts Nickel (II) quantitatively (99.83%) into n-amyl alcohol from an aqueous solution of pH 7.2 – 8.8. The n-amyl alcohol extract shows an intense peak at510nm (λ max). Beer’s law is obeyed over the Ni (II) concentration range 1.0–6.0ug/ml. The molar absorptivity is 4412 L mole^-1cm^-1 at 510 nm. And Sandel’s sensitivity is 13.3 ng/cm².  The composition of extracted species is found to be 1:2 (Ni: HBITSC) by Job’s continuous variation and Mole ratio method. Interference by various ions has been studied. The proposed method has been applied for determination of Ni (II) in alloy samples.
