摘要：The preparation of porous ceramic with waste porcelain powder as aggregate research. The influence of the amount of Sesbania powder and the calcination temperature on the adsorption performance of porous ceramics was investigated. The effect of the amount of porous ceramic and the adsorption time on the removal rate of Cu in wastewater containing Cu was investigated.The results showed that the adsorption properties of porous ceramics were related to the calcination temperature and the amount of Sesbania powder. The suitable calcination temperature and the amount of Sesbania powder were 600 °Cand 4 wt%, respectively.The removal rate of Cu in water samples increases with the increase of the amount of porous ceramics and the increase of adsorption time. The suitable amount of porous ceramics is 10 g/L and the adsorption time is 35 min. XRD characterization showed that the crystal particles were grown by calcination, and the properties of porous ceramics were stable before and after adsorption.
