چکیده
|
The work focuses on the removing of cu(ii) from aqueous solution by linde f(k) zeolite. the zeolite is synthesized from fly ash by hydrothermal process. the adsorption experiments discuss several factors including the optimal solution ph, zeolite dosage, adsorption temperature, adsorption kinetics and adsorption isotherm equation. the results show that, the optimal solution ph is 6 and the efficient zeolite dosage is 4g/l. higher reaction temperature could favor the removal of cu(ii). the adsorption of cu(ii) on linde f (k) zeolite is monolayer adsorption. the experiment data could be calculated by pseudo-second-order model and langmuir isotherm. the adsorption process is endothermic and spontaneous and the system disorder increases with temperature.
