چکیده
|
Tarap core (tc) was used to investigate its ability as an adsorbent for the removal of crystal violet (cv) dye from aqueous solution. batch experiment was done to evaluate parameters such as effects of contact time,dosage,dye concentration,temperature,ph and ionic strength on the adsorption of cv onto tc. langmuir,freundlich and tempkin isotherm models were used to investigate the adsorption process and the langmuir model was found to best fit the experimental data with maximum monolayer adsorption capacity of 217 mg g-1. the optimum conditions for the experiments were 2 h contact time and without any ph adjustment. thermodynamics study indicated that the adsorption of cv onto tc was feasible and endothermic in nature. from the kinetics study,film diffusion and pseudo 2nd order model might play major roles in the adsorption mechanism. © 2017,university of mohammed premier oujda morocco.
