Using diatomite as the main material, diatomite-based porous ceramsite was prepared by wet grinding, molding by rolling and high-temperature calcinations. The structure and properties were characterized by X-ray diffraction, Scanning Electron Microscope, Mercury Injection Apparatus and so on. The ultraviolet-visible spectrophotometer was used to analyse the adsorption properties of diatomite-based porous ceramsite on Cu2+. The results show that the pore size distribution of materials is 300~3500 nm, the specific surface area is 6.14 m2/g, and the pore porosity is 47.8%. Plenty of unsaturated bonds, such as -OH, Si-O-Si and O-Si-O, cluster on the surface of ceramsite. The removal rate of Cu2+ reaches 92.5%.Keywords
