With the development of industrial utilization of chromium, the problem of chromium pollution is becoming more and more serious. Based on the advantages of easy separation of metal mesh, Al/Cu bimetallic mesh materials were prepared by chemical deposition method to realize the rapid removal of Cr(Ⅵ). Thereaction temperature, solution pH, Al/Cu bimetallic dosing quantity and other conditions were optimized by static test system. The Al/Cu bimetallic mesh material was characterized. It was found that the loose coral-like particles of Cu coating grew on the surface of the Al mesh in situ. The static test of Cr(Ⅵ) removal showed that the removal rate of Cr(Ⅵ) by Al/Cu bimetallic network can reach more than 90% in a wide pH range of 3.0~9.0.When the dosage of Al/Cu bimetallic network was 3 pieces, the Cr(Ⅵ) initial concentration was 5 mg/L, and the reaction temperature was 40℃, the removal effect of Cr(Ⅵ) in water worked best.Mechanism analysis showed that a large number of galvanic cells were formed on the surface of Al/Cu bimetallic network to promote Al⁰ corrosion and release electrons to reduce Cr(Ⅵ) to Cr(Ⅲ).The formation of[H]_abs on the surface of bimetallic mesh further promoted the reduction of Cr(Ⅵ) to Cr(OH)₃ or deposits in the form of flocs on the surface of bimetallic network to remove Cr(Ⅵ) from aqueous solution.The easily separated Al/Cu bimetallic mesh is helpful for the rapid removal of Cr(Ⅵ) in groundwater and other water bodies, and has a good prospect of engineering application.
