Copper electrolyte adsorption, impurity removal and purification method

The invention discloses a copper electrolyte adsorption, impurity removal and purification method which is characterized by comprising the following steps: by taking oxides of antimony or/and bismuth and hydrates thereof as adsorbents, selectively adsorbing impurities As, Sb and Bi from copper electrolyte or from a solution in which cathode copper is produced through electrodeposition of the copper electrolyte or from a crystallizing mother solution obtained after copper sulfate is evaporated, concentrated and crystallized in the copper electrolyte. According to desorption of loaded adsorbents and regeneration of the analyzed solution, the adsorbents and analytical solution can be recycled, and the adsorbed impurities As, Sb and Bi can be recycled. The method has the advantages of simple process, simple and convenient operation, low production cost, good purification effect and the like, side effects on a main process are avoided, a traditional electrodeposition copper and impurity removal copper electrolyte purification process can be completely substituted, black copper sludge and black copper plate in the copper electrolyte purification process are completely eliminated, emission of harmful substances such as AsH3 is avoided, pollution is reduced, and the environment is protected.
