Abstract: The experimental study using a titania  compound adsorbent to dispose the chromium in waste water is compared with using the active carbon. The result shows,if the content of the chromium in waster water is 80 mg/L and the adsorbent is titania, the removal rate of chromium will reach 99.5%, which is obviously higher than using active carbon adsorbent; what's more, the desorption rate of chromium can reach 99.6%, and the adsorbent can be used again after regeneration.

Key words: titania compound adsorbent, waste water containing chromium, removal rate of adsorption, desorption rate
