Abstract: The possibility of using 3-phenyl-2,4-thiazolidinedione (L) for the photometric determination of nickel (II) has been studied. Dichloroethane, chloroform and carbon tetrachloride were the best extractants. With a single extraction with chloroform, 97.3% of nickel is recovered as a complex. The complex of nickel (II) is extracted into chloroform in the range of pH 4.2-6.0. The maximum analytical signal in the complexation of nickel with L is observed at 492 nm. The molar absorption coefficient is 2.65 × 104. The ratio of components in the complex is Ni: L = 1: 2. The extract of the nickel complex obeys the basic law of absorption at a concentration of 0.5-15 μg / ml. Based on the results of spectrophotometric studies of nickel (II) with L, methods for determining nickel in various objects have been developed.
