Basic copper carbonate was prepared with copper nitrate and ammonium bicarbonate as raw materials. Then active copper oxide was prepared by basic copper carbonate after high-temperature roasting. The properties of the active copper oxide were characterized by X-ray diffraction (XRD), purity determination and inductively coupled plasma atomic emission spectroscopy (ICP-AES). The purity of active copper oxide prepared by this method could reach more than 99.3%, higher than the universal national standard of analytical reagent. And impurity content was far superior to the universal national standard of analytical reagent. Hence it could meet the requirements of high-purity, low-impurity for electroplating.
