Fabrication of bamboo fiber-based adsorbent by radiation grafting and rapid adsorption of phosphate
Quaternary ammonium salt modified bamboo fiber was prepared by radiation grafting of methacryloxyethyltrimethyl ammonium chloride on the bamboo fiber. The modified bamboo fiber was characterized by scanning electron microscopy, Fourier transform infrared spectroscopy, and thermogravimetric analysis....

| description | Quaternary ammonium salt modified bamboo fiber was prepared by radiation grafting of methacryloxyethyltrimethyl ammonium chloride on the bamboo fiber. The modified bamboo fiber was characterized by scanning electron microscopy, Fourier transform infrared spectroscopy, and thermogravimetric analysis. The results showed that the quaternary ammonium salt monomer was successfully grafted on the surface of the bamboo fiber. The adsorption behavior of phosphate on the modified bamboo fiber was examined by batch and fixed-bed column adsorption experiments. The adsorption kinetics of phosphate on the modified bamboo fiber followed the pseudo-second-order kinetic model with an equilibrium time of 20 min. The maximum adsorption capacity reached 67.48 mg/g when using the Langmuir model which was well fitted with the adsorption isotherms data. The fix-bed column experiments showed that the Thomas and Yoon-Nelson models explained the experimental data effectively. Moreover, the modified bamboo fiber can be effectively regenerated for further use. Such high adsorption and desorption efficiency of the modified bamboo fiber is advantageous for phosphate adsorption in practical applications. |
