3-Hydroxy-3-n-propyl-1-(4-sulphonamidophenyl)triazene has been used for spectrophotometric determination of Nickel(II) at 400 nm, keeping the pH between 6.9 to 7.3. The Beer’s law is obeyed in the range 1x10^-5 to6x 10^-5 M. The molar absorptivity and Sandell’s sensitivity values are 6743 dm³ mol^-1 cm^-1 and 8.61 ng cm^-2, respectively. The Nickel (II) has been determined successfully even in presence of upto 100 ppm of various interfering cations and anions. The reagent forms complex with iron at ratio of 1:2. The composition of complex was determined by Job’s method and Mole ratio method of Yoe and Jones. The value of log β found from two different methods were 9.57 and 9.53 respectively.
