{Abstract}: A new nanostructured amino-functionalized magnetic bacterial cellulose/activated carbon(BC/AC)composite bioadsorbent(AMBCAC)was prepared for removal of Pb~(2+)and methyl orange(MO)from aqueous solution.The results demonstrated that the equilibrium adsorption capacity(q_e)for Pb~(2+)obviously increases by 2.14 times after introduction of amino groups,the optimum p H for Pb~(2+)and MO adsorption was 5.0 and 3.0,respectively,and the q_eof AMBCAC was 161.78 mg g~(-1)for Pb~(2+)and 83.26 mg g~(-1)for MO under the optimal conditions in this investigation.The kinetics and adsorption isotherm data of the sorption process were well fitted by pseudo-second-order kinetic model and Langmuir isotherm respectively.The thermodynamic results(the Gibbs free energy change G<0,the enthalpy change H>0,the entropy change S>0)implied that the adsorption process of Pb~(2+)and MO was feasible,endothermic and spontaneous in nature.These results support that the AMBCAC composite developed in this work can provide a cheap and efficient way for easy removal of both Pb~(2+)and MO as a promising adsorbent candidate for wastewater treatment.
