Abstract

In this study, industrial waste tailings were used as the main raw material to prepare porous ceramic by injection molding. The porous ceramic samples were surface treated by γ-Aminopropyl triethoxysilane solution to be used as adsorbent to remove Cu(II) from solution. The effects of sintering technology on properties of porous ceramic samples were studied. Meanwhile, the effects of test conditions on the adsorption characteristics of samples were also studied. The samples were analyzed by X-ray diffraction, FTIR, and SEM. Atomic absorption spectrophotometer was used to determine the changes of Cu(II) concentration in the aqueous solution before and after adsorption. The results show that the compressive strength of the samples is increased with the increase of sintered temperature and extension of holding time. The average pore diameters of the samples are decreased and concentrated between 0.1 and 0.2mm with the increase of sintered temperature. The removal rates and the adsorption capacities of the samples to Cu(Ⅱ) are increased with the increase of solution temperature, increase of pH value of the solution and the extension of the test time
