Wheat straws were modified by 3-chloro-2-hydroxypropyl trimethylammonium chloride (CTA) to obtain aminated wheat straw St-N'. The optimum synthetic conditions were determined to be NaOH with 30% mass fraction, CTA of 100 mL, reaction temperature of 80℃, and reaction time of 3 h, which was verified by orthogonal experiments. Nano-sized hydrous zirconium oxides (HZO) were immobilized into St-N' by an in situ precipitation method to obtain the nanocomposite St-N'-Zr. The SEM, TEM, XRD, and BET results indicated that the nano-sized HZO with 50-100 nm sizes were uniformly loaded onto the inner surface of the biomass-based carrier St-N' that was amorphous in nature. A Langmuir adsorption isotherm fitted the adsorption process well, and the maximum adsorption amount was calculated to be 33.90 mg·g |
