Popis: | 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 to 6x 10-5 M. The molar absorptivity and Sandell's sensitivity values are 6743 dm 3 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 ² found from two different methods were 9.57 and 9.53 respectively. |
