Abstract: The porous ceramics filtering materials with red mud derived from Bayer process is used as adsorbent to investigate the removal rate of copper in waste water and the regeneration of saturated porous ceramics. The research indicated that the porous ceramics filtering materials with red mud derived from Bayer process has a significant adsorbing performance and lasting quality. The adsorption-saturated ceramics can be restored to be fresh ceramics with fresh adsorption performance after regenerating 3 times in static status in a nitric acid solution of pH = 3. The copper removal from the waste water with the porous ceramics of red mud derived from Bayer Process has a significant advantage in techniques，economics and re-utilization of resources，and it is suitable for large-scale application.

Key words: Porous ceramics with red mud derived from Bayer process, Copper-contained waste water, Adsorption regeneration of porous ceramics
