AB  - This study was conducted with a batch reaction to equilibrium isotherm, kinetic 
      and thermodynamic parameters on adsorption of bromocresol purple (BCP), acid red 
      66 (AR 66) and acid blue 40 (AB 40) from aqueous solution by using activated 
      carbon with nanopores. Freundlich and Temkin isotherm models were used to 
      evaluate the suitability of isotherm for adsorption equilibrium data. The 
      adsorption equilibrium was best fitted by Temkin model. The Freundlich separation 
      factor values indicated that adsorption on the nanoporous activated carbon could 
      effectively treat three dyes. The kinetic analysis of the adsorption process 
      confirmed that it was more consistent with the pseudo second order model. The 
      intraparticle diffusion was rate limiting step. The adsorption process of three 
      dyes were endothermic because they were positive enthalpy values. The free energy 
      values of three dyes decreased with increasing temperature, so that the 
      spontaneity becomes higher with temperature increase. The activation energy value 
      of three dyes were confirmed the physical adsorption.
