Resumen : | spectrophotometric method for determination of nickel in copper-base alloy with 2-(2-thiaxolylaxo)-p-cresol (TAC) is described. The interferences of foreign ions can be eliminated by masking with a mixture of sodium tartrate and sodium thiosulphate. The nickel-TAC complex has low solubility in water, but is soluble in aqueous ethanol. Beer’s law is obeyed for 20-70 pg of nickel in 50 ml of solution, at pH 5.7. The molar absorptivity at 580 nm is 2.6 x IO4 l.mole-‘.cn-‘. The method has been applied successfully to determination of nickel in reference samples. |
