AB  - Cyclodextrin-ionic liquid polymer (betaCD-BIMOTs-TDI) was firstly synthesized using 
      functionalized beta-Cyclodextrin (CD) with 1-benzylimidazole (BIM) to form 
      monofunctionalized CD (betaCD-BIMOTs) and was further polymerized using toluene 
      diisocyanate (TDI) linker to form insoluble betaCD-BIMOTs-TDI. SEM characterization 
      result shows that betaCD-BIMOTs-TDI exhibits macropore size while the BET result 
      shows low surface area (1.254 m(2)g(-1)). The unique properties of the ILs allow 
      us to produce materials with different morphologies. The adsorption isotherm and 
      kinetics of 2,4-dichlorophenol (2,4-DCP) onto betaCD-BIMOTs-TDI is studied. 
      Freundlich isotherm and pseudo-second order kinetics are found to be the best to 
      represent the data for 2,4-DCP adsorption on the betaCD-BIMOTs-TDI. The presence of 
      macropores decreases the mass transfer resistance and increases the adsorption 
      process by reducing the diffusion distance. The change in entropy (DeltaS degrees ) and heat 
      of adsorption (DeltaH degrees ) for 2,4-DCP on betaCD-BIMOTs-TDI were estimated as -55.99 J/Kmol 
      and -18.10 J/mol, respectively. The negative value of Gibbs free energy (DeltaG degrees ) 
      indicates that the adsorption process is thermodynamically feasible, spontaneous 
      and chemically controlled. Finally, the interactions between the cavity of 
      betaCD-BIMOTs and 2,4-DCP are investigated and the results shows that the inclusion 
      of the complex formation and pi-pi interaction are the main processes involved in 
      the adsorption process.
