A simple, sensitive and selective extractive spectrophotometric method was developed for the determination of Ni (II) in various water and alloy samples using newly synthesized reagent 3-(1-benzhydrylazetidin-3-yl) 5-isopropyl 2-amino-1,4-dihydro-6-methyl-4-(4-nitrophenyl)pyridine-3,5-dicarboxylate Ni(II) forms a yellow colored complex with 3-(1-benzhydrylazetidin-3-yl) 5-isopropyl 2-amino-1,4-dihydro-6-methyl-4-(4-nitrophenyl)pyridine-3,5-dicarboxylate in acetate buffer medium (pH 7.5). Under optimum conditions the maximum absorption of the ethanol extracts were measured at 445 nm. Beer\\\'s law was obeyed in the range of 0.5 to 1.0 µg mL-1 of Nickel. The molar absorptivity and Sandell’s sensitivity of the complex were as 6.0×104 l mol-1 cm-1 and 1.02 µg cm-2 respectively. . The detailed study of various interfering ions made the method more sensitive. The method was successfully applied for the determination of Ni (II) in water and alloy samples.
