A new reagent o-chlorophenylazo-bis-acetoxime has been used for spectrophotometric determination of Ni (II). Nickel forms a 1:2 (Ni: R) ethanol soluble greenish yellow complex with the reagent. The working wavelength was taken at 370 nm (ε-2451) in the pH range 7.3-7.9. Beer's law obeyed between 0.117 - 0.939 ppm and Sandell's sensitivity is 23.09 ng/cm2. The values of log β found from the two different methods were 8.95 and 8.76, respectively. Interference of 24 diverse ions has been examined.
