| Abstract: | The absorbability of 13X zeolite on Ni 2+ in wastewater was experimentally studied. The absorption rate, isotherms, capacity and effects of such factors on the absorbability as pH value, Ni 2+ concentration in the wastewater, temperature, time and dosage of wastewater were characterized separately. The mechanism for adsorption of 13X zeolite on Ni 2+ was also studied. The results show that at ambient temperature, the adsorption capacity of 13X zeolite on Ni 2+ in wastewater was 49.7 mg/g zeolite in 15 minutes. The adsorption isotherm for the process exhibits Langmiur behavior, and the ion exchange and surface complex were suggested to be the major adsorption mechanisms in the experiments. |
