Peanut shell Cellulose Xanthate (PCX) was prepared by reacting with carbon disulphide after mercerized by sodium hydroxide solution. The preparing conditions (hydroxide solution concentration, carbon disulphide dosage, temperature) were optimized in this study. And the effects of PCX amount and contact time on the removal of Cd (II) ion from aqueous solution was studied,the results indicated that when the initial Cd (II) ion concentration was 10mg/L, the adsorption capacity of PXC was high effective with the PCX amount was 1g/L and the contact time was 1.5h,the equilibrium adsorption capacity of PCX was 9.87 mg/g and the removal rate of Cd (II) ion was 98.72%.Then the regeneration capacities of PCX adsorbent was investigated, the results indicated that the removal rate of Cd (II) ion was more than 75% after regeneration. All the results indicated that the PCX can be used as a low cost but effective biosorbent for heavy metals remediation.
