Abstract

The 2-(5-Bromo-2'-thiazolylazo)-5-dimethyl amino benzole acid has been synthesized. The properties of the reagent and its complex formation reaction with Ni(Ⅱ) are studied. A sensitive spectrophotometric method for the determination of micro amounts of Ni(Ⅱ) has been developed. The optimum condition for determination, the linear calibration range and the interference of various foreign ions are reported. The composition, the molar absorptivity and the stability constant of MR complex are determined. The method has been applied to determination of Ni(Ⅱ) in alloy steel with satisfatory results.
