Graphene oxide modified with carboxymethyl cellulose for high adsorption capacities towards Nd(III) and Ce(III) from aqueous solutions

Abstract This work addresses a simple method to functionalize graphene oxide with sodium carboxymethyl cellulose using tetraethyl orthosilicate as linker for rapid and significant removal of Nd(III) Ce(III) from aqueous solutions. The prepared composite (GO–CMC) was characterized by different techniques confirm the modification adsorption process. sorption performance GO–CMC evaluated absorbent materials. experimental results demonstrated that process excellently fitted pseudo-second-order kinetic model. were also analyzed isotherm models. According Langmuir model, capacities at pH 3.0 661.21 436.55 mg/g Ce(III), respectively. thermodynamic indicated two examined metal ions endothermic spontaneous. regenerated has similar percentage original composite. These confirmed could be used an effective adsorbent certain multielement
