| Abstract: | With natural sesame leaves as low-cost adsorbent,the adsorption of methylene blue(MB) from aqueous solution was studied by batch adsorption technique.The adsorption experiments were carried out under different conditions of solution pH,sesame leaves dose,and temperature.The pseudo-first order,pseudo-second order,and the intraparticle diffusion models and Langmuir,Freundlich and Dubinin-Radushkevich(D-R) isotherms models were used to describe the kinetic data.The experimental results show that the pseudo-sec... |
