Abstract
Nickel(Il) reacts with benzilditbiosemicarbazone in aqueous
dimethyl formamide solution in ammonium chloride ammonium
hydroxide buffer of pH 9.0 giving yellowish orange precipitate. The
1 : 1 complex in chloroform has a maximum absorption at 410 nm
and is stable for 48 h. Beer's law is obeyed in the range 0.1-1.6
μg/ml of nickel(II). The effect of various foreign ions is also studied.
The method is applied for the estimation ot micro amounts of
nickel(lI) in nichrome wire and steel samples and the results are
compared with atomic absorption spectrophotometric method.
