摘　　要：This paper discusses the elaboration of adsorbents from oil shale.The experimental designs a response surface methodology(RSM),which has been applied to optimize the significant preparation factors,such as tempera-ture,time,and the activating agent percentage.The results obtained from central composite design(CCD)revealed that the interaction between the factors was significant for the maximum quantity of adsorption(response).Planned results have shown that a maximum quantity of adsorption for methylene blue is 65 mg/g,which could be achieved with a temperature of 275℃over 2 h and a percentage of the activating agent of 45%.The predicted values agreed with the experimental finding,with a determination coefficient(R2)of 0.96.The model has been validated by experi-ments after conditions optimization.The new material(RHO)was characterized by cation exchange capacity,zero charge pH,surface functions,X-ray fluorescence,specific surface area,and electron microscopy analysis.Phenol adsorption was determined using Langmuir,Freundlich and Temkin,which were used to describe the adsorption iso-therms.The adsorption capacity of the material was about 263 mg/g,and the kinetic studies showed rapid adsorption.
