摘要
Abstract
Flavedo was modified by ethanol,sodium hydroxide and calcium chloride for preparing biosorbent to remove neutral red in waste water.Effects of adsorption time,pH value,initial concentration of dye,temperature and absorbent dosage on the adsorption capacity and adsorption kinetics were investigated.In the conditions ofpH 7,the initial concentration of 1 200 mg·L-1,the dosage of 0.1 g,the contact time for 5 h,the maximum absorption capacity of the modified flavedo could reach 478.60 mg·g-1 at 20℃.The isothermal adsorption fitted for the Freundlich adsorption model.Adsorption kinetics followed by the pseudo-second-order kinetic model.关键词
