Utilization of natural zeolite as ion-exchange and sorbent material in the removal of iron
چکیده انگلیسی

The batch removal of Fe3+ from aqueous model solution under different experimental conditions using Jordanian natural zeolite (JNZ) has been investigated. The influences of contact time, metal initial concentration, adsorbent dosage concentration, and temperature have been studied. The adsorption efficiencies are found to be contact time dependent, increasing the contact time in the range of 1–150 min. The sorption equilibrium has attained between 60 and 150 min. The optimum adsorption has taken place at temperature 30°C. The equilibrium adsorption capacity of JNZ adsorbent used for Fe3+ were measured and extrapolated using Langmuir and Freundlich isotherm models and the experimental data are found to fit Langmuir more than Freundlich.
