Adsorption Kinetics of Modified Pomelo Peel Cellulose towards Lead Ions

Succinic anhydride modified pomelo peel cellulose as biosorbents,Cell 5 and Cell 6 were used to remove lead ions from aqueous solutions.Adsorption equilibrium and kinetics of lead ions from aqueous solutions onto modified pomelo peel cellulose were investigated.Adsorption kinetics of lead ions onto Cell 5 and Cell 6 obeyed pseudo-second-order equation.Adsorption equilibrium studies demonstrated that the bio-adsorption complied with Langmuir isotherm model.The maximum adsorption capacities of Cell 5 and Cell 6 were 142.86 mg/g and 181.82 mg/g,respectively.These investigations suggest that modified pomelo peel cellulose is an attractive candidate for removing lead ions from aqueous solutions.
