主　　题：biosorption chromium Kappaphycus alvarezii 

摘      要：The Cr（III） sorption experiments onto Kappaphycus alvarezii waste biomass were conducted at different pH values（2-6） under the conditions of initial metal concentration of 10-50 mg/L and the chemical compositions of Cr-Cu and *** Cr（III） sorption capacities were slightly dependent on pH,and the maximum sorption capacity was 0.86 mg/g at pH *** sorption capacities increased with increase in the initial metal concentration,whereas it was suppressed by the presence of Cu（II） and Cd（III） in the *** Cr（III） sorption equilibrium was evaluated using Langmuir,Freundlich and BET *** sorption mechanisms were characterised using scanning electron microscopy and Fourier transform infrared *** main mechanisms were ion exchange coupled with a complexation *** alvarezii waste biomass represents a potential for Cr（III） ion removal from aqueous solution.
