The invention discloses a kind of methods for preparing magnetic cellulose aeroge using waste paper, the waste paper fibre in life is used to prepare ultralight, porous gas magnetic hydrophobic aeroge adsorbent material as raw material, waste paper regenerated cellulose gel is prepared using microwave-assisted ion liquid dissolving method, it is modified by magnetic modification and hydrophobic oleophobic, obtain dark red waste paper fibre element aeroge.Magnetic cellulose aeroge of the invention effectively removes the Some Organic Pollutants and oily substance leaked in water, absorbency is high, oil suction is thorough, adsorbent material is nontoxic, easy-to-use using magnetic capture method simplicity, cause secondary pollution small, the preparation method has a simple process, mild condition, passes through conventional industrial equipment and cheap raw material, and change " useless " can be realized as " treasured ", and production process is excluded without " three wastes ", has extensive application value and social effect. |
