Open publisher page 0 citations

Abstract

This paper introduces the use of ZSM-5 zeolite as the adsorbent to processing the wastewater of aniline,and to study the amount of molecular sieve at room temperature,adsorption time,pH of solution,temperature on the adsorption efficiency of aniline.The adsorption kinetics were also discussed.Langmuir,Freundlich and Dubinin-Radushkevick isotherms were used to fit the adsorption equilibrium data and the adsorption process followed the models of Langmuir and Freundlich.The kinetics data were fitted better with the pseudo-second-order kinetic model.
