| Abstract: | A new composite of zeolite/actived carbon was prepared from the elutrilithe,a by-product in coal production process.When varying the preparation condition,the composites of zeolite A and/or zeolite X and activated carbon were obtained.Then characterize the samples obtained by means of XRD,N2(77 K) adsorption,and adsorption for water and hexane.The composite has not only a dual micro-and mesoporous structure but also a twofold hydrophobic and hydrophilic property.In addition,it has ion exchange property.Adsorption experiments present that the new composite has high adsorption capacities for H2O and hexane.The phenol and Cr3+ in the waste aqueous solution can be removed by the composite. |
