英文摘要To further improve the adsorption capacity of chitosan (cts), a series of novel chitosan/organomontmorillonite nanocomposites (cts/ommt) were synthesized and the adsorption abilities for congo red (cr) investigated in this study. the nanocomposites were characterized by fourier transform infrared spectroscopy (ftir), x-ray diffraction analysis (xrd), scanning electron microscopy (sem) and transmission electron microscopy (tem), and the results indicated that an exfoliated nanostructure was formed in cts/ommt nanocomposites. compared with the adsorption capacity of ommt (192.4 mg g(-1)), cts/ommt with an amount of cetyltrimethylammonium bromide equal to 0.75 cec of mmt and molar ratio of cts to ommt of 1:10 exhibited the higher adsorption capacity (290.8 mg g(-1)). the adsorption behaviours of ommt and cts/ommt showed that the adsorption kinetics and isotherms were in good agreement with a pseudo-second-order equation and the langmuir equation, respectively. the ir spectra revealed that a chemical interaction occurred between cts/ommt and cr. the adsorption capacity of cts/onimt nanocomposite was higher than that of other absorbents; this study suggested that the cts/ommt nanocomposite could be used as an adsorbent to remove cr dye from aqueous solution.
