Adsorption experiments of acid blue 40 dye by coconut shell activated carbon were performed adsorption volume, pH, initial concentration, contact time and temperature as adsorption variables. Adsorption equilibrium data were analyzed using Langmuir, Freundlich and Temkin adsorption isotherm models. Adsorption equilibrium of acid blue 40 was best agreement Langmuir isotherm model. Langmuir’s separation factor (+0.2328~0.6753) was found that adsorption of acid blue 40 by activated carbon was an appropriate removal method. The Temkin’s adsorption energy is 5.795~6.432 J/mol, indicating physical adsorption( |
