柚子皮活性炭对刚果红吸附性能试验
Congo red adsorption from wastewater by activated carbon of pomelo peel
摘要
Abstract
Activated carbon adsorbent was prepared from pomelo peel by activation with zinc chloride.The ab-sorbing effect of activated carbon on Congo red is studied.The results suggested that when pH=1 1 ,the adsorp-tion was the best.The higher the dosage,the less the adsorbing capacity on Congo red was.Adsorption could be increased by enhancing the initial Congo red concentration.It was found that the adsorption of Congo red was of physical nature,spontaneous and the adsorption got to the balance basically after 60 min.When isothermal adsorption of Congo red used the Freundlich isothermal model fitting,the adsorption kinetics process of Congo red satisfactorily follows the second order kinetic model.However,the pore diffusion of Congo red in pomelo peel activated carbon adsorption was not the only rate controlling step,the adsorption process may be controlled by multiple steps together.关键词
