Abstract

A new spectrophotometric method using isovanillin thiosemicarbazone (IVTSC) is proposed for the determination of Ni(II) at microgram level. IVTSC reacts with Ni(II) at pH 9 to form a yellow coloured complex which was extracted in n-butanol which shows maximum absorption at 400 nm. The molar absorptivity and Sandell's sensitivity were calculated to be 6.4060 × 10³ L mol^–1 cm^–1 and 0.000109 μg cm^–2 respectively. The stoichiometry of the complex was found to be 1 : 2.
