AB  - Rice straw activated carbon has been used for nitrate removal 
  from aqueous solution. Results showed that increasing adsorbent concentrations 
  increase the adsorption efficiency and decrease the adsorption capacity. At 
  low adsorbent dose all types of sites are entirely exposed for adsorption and 
  the surface gets saturated faster. At higher particle concentrations there is 
  larger fraction of higher energy sites becoming unoccupied. Langmuir-Freundlich 
  Adsorption Isotherm Model gave higher fitting to the experimental data compared 
  to Freundlich and Langmuir isotherms. This due to Langmuir-Freundlich Model 
  has three fitting parameters which not restricted to monolayer of molecules 
  as it was in the Langmuir isotherm. A comparative study on the nitrate adsorption 
  revealed that the prepared carbon had better nitrate adsorption capacity (82 
  mg g<SUP>-1</SUP>) as compared to other adsorbents. This suggests that straw 
  based activated carbon is efficient nitrate adsorbents and that they possess 
  good potential for nitrate removal in wastewater treatment.
