| 英文摘要 | xylan-rich hemicelluloses-based hydrogel was developed as a novel porous bioadsorbent by graft co-polymerization of acrylic acid (aa) and xylan-rich hemicelluloses for adsorption of heavy metal ions (pd2+, cd2+, and zn2+) from aqueous solutions. the chemical structure, the interaction between the hydrogel and metal ions, and the porous structure of xylan-rich hemicelluloses-g-aa hydrogel were revealed by fourier transform infrared spectroscopy and scanning electron microscopy. the effects of aa and cross-linker dosage, ph value, contacting time, and initial concentration of metal ion on the adsorption capacity were studied. the adsorption equilibrium time was about 60 mm from the adsorption kinetics study. the maximum adsorption capacities of pd2+, cd2+, and zn2+ were 859, 495, and 274 mg/g, respectively. furthermore, xylan-rich hemicelluloses-g-aa hydrogel also exhibited highly efficient regeneration and metal ion recovery efficiency and can be reused without noticeable loss of adsorption capacity for pd2+, cd2+, and zn2+ after quite a number of repeated adsorption/desorption cycles. |
