摘要：

A new UV-visible spectrophotometric method was developed for the determination of copper (II) in industrial wastewater samples. The method is based on complex formation of copper (II) with sulfanilic acid in acidic medium a room temperature: The complex showed maximum, absorption at a wavelength of 380 nm with a molar absorptivity value of 6.7x10(-2) mol(-1) cm(-1). Beer's law is obeyed in the concentration range of 0.3 to 2.1 ppm. Interferences due to zinc (II), cadmium (II), nickel (II), cobalt (II), chromium (III) and several anions were investigated. The proposed method was successfully applied to the determination of copper (II) in industrial effluent samples.
