摘要：Activated carbon were used as the adsorbent, in this study, for the removal of textile dye acid green 1 (AG1) from aqueous solutions. Effects of various experimental parameters, such as adsorbent dose, contact time, initial dye concentration, and initial pH solution are studied. The removal of AG1 effluent is a rapid process. At pH 2 and at room temperature, the adsorption equilibrium is reached after 2 hours and the kinetics follow a pseudo-second order model. The adsorption isotherm is in good agreement with the Langmuir model, is of L-type. The adsorption of dye on the surface of activated carbon was done in monolayer. This mechanism has been confirmed by IR spectroscopy and Scanning Electron Microscopy. The removal of acid green 1 by activated carbon is total (100 %) at optimized conditions and the maximum adsorption capacity was reached 121.5 mg/g.
