Stability constant, composition of copper (Ⅱ)-oxamidoxime complex were determined by spectrophotometric method. The ratio of copper (Ⅱ) and oxamidoxime in the above complex was 1 : 1, and its stability constant was calculated to be 2.4 × 1022. The complex solution gave constant absorbancy between the pH range of 4.5 to 6 at 600 mμ in which Beer's law applicable in the concentration range of 0.3 to 2.0 ppm studied in this work. It was noted that some metals such as Fe(Ⅲ), Ni(Ⅱ), Co(Ⅱ), U(Ⅵ) interfere copper determination by this method.
