%X The process of biosorption and the adsorbing mechanisms of Fe3 O4/Sphaerotilus natans to Cr(VI) were studied. The experiment results showed that pH value was main influencing factors on adsorption to Cr(VI). In the range of pH 2 to 3, the adsorbance of the composite biosorbent to Cr(VI) is 0.0217 mmol/g. The regeneration efficiency is 90% when the composite biosorbent was regenerated by HCl solution. --CONH2-- and --NH-- were principal activated groups of composite biosorbent. Cr(VI) can primarily combine with the surface of Fe3O4/Sphaerotilus natans by electrostatic attraction.
