Study of Adsorption Characteristics of Methylene Blue onto Activated Carbon Made by Salix Psammophila

Salix psammophila activated carbon was prepared by three different kinds of activator, and their adosorption of Methylene Blue (MB) have been investigated. Experiments were explored the effects of the time, temperature and pH value to adsorption of Methylene Blue, and adsorption isotherms and adsorption kinetics were obtained. The experimental results indicated that adsorption of activated carbon were found to conform to the pseudo-second-order kinetics with good correlation and fitted well with the Langmuir isotherm. The higher pH value and temperature are conducive to the conduct of adsorption.
