      solution: adsorption behavior and mechanisms.

AB  - An andic soil, akadama clay, was modified with nickel oxide and tested for its 
      potential application in the removal of cesium from aqueous solution. Scanning 
      electron microscope (SEM), energy dispersive X-ray spectroscopy (EDS), and powder 
      X-ray diffraction (XRD) results revealed the nickel oxide was successfully 
      grafted into akadama clay. N2 adsorption-desorption isotherms indicated the 
      surface area decreased remarkably after modification while the portion of 
      mesopores increased greatly. Thermogravimetric-differential thermal analysis 
      (TG-DTA) showed the modified akadama clay had better thermostability than the 
      pristine akadama clay. Decreases in cation exchange capacity (CEC) and 
      zeta-potential were also detected after the modification. Adsorption kinetic and 
      isotherm studies indicated the adsorption of Cs+ on the modified akadama clay was 
      a monolayer adsorption process. Adsorption capacity was greatly enhanced for the 
      modified akadama clay probably due to the increase in negative surface charge 
      caused by the modification. The adsorption of Cs+ on the modified akadama clay 
      was dominated by an electrostatic adsorption process. Results of this work are of 
      great significance for the application of akadama clay as a promising adsorbent 
      material for cesium removal from aqueous solutions.
