AB  - The chitosan/fly-ash-cenospheres/gamma-Fe(2)O(3) (CTS/gamma-Fe(2)O(3)/FACs) magnetic 
      composites were prepared by microemulsion process. The resulting composites were 
      characterized by XRD, FT-IR, SEM, TGA, DTG and VSM, and the results indicated 
      that CTS/gamma-Fe(2)O(3)/FACs exhibited magnetic property (M(s)=6.553 emu g(-1)) and 
      thermal stability, and composed of chitosan wrapping magnetic gamma-Fe(2)O(3) and 
      fly-ash-cenospheres (thickness of the cross-linked chitosan was about 5.2 mum). 
      Then the CTS/gamma-Fe(2)O(3)/FACs were employed as adsorbents for the fast removal of 
      bisphenol A (BPA) and 2,4,6-trichlorophenol (TCP) from aqueous solutions. The 
      adsorption performances of CTS/gamma-Fe(2)O(3)/FACs were investigated by batch mode 
      experiments with respect to pH, temperature, initial concentration, contact time 
      and binary solution system. The Langmuir isotherm model was fitted to the 
      equilibrium data better than the Freundlich model, and the kinetic properties 
      were well described by the pseudo-second-order equation. The effects of binary 
      solution systems also demonstrated that BPA adsorption onto CTS/gamma-Fe(2)O(3)/FACs 
      was more affected by the simultaneous presence of competitive phenolic compound 
      than that of TCP. In addition, the resulting composite reusability without 
      obviously deterioration in performance was demonstrated by at least three 
      repeated cycles.
