| Abstract: |
| UiO-66/CF was prepared by hydrothermal synthesis method with cotton pulp fiber （CF） as the base material and Zr6O4（OH）4-（BDC）6 （UiO-66） as the metal organic framework material （MOF）. UiO-66/CF was modified by octadecylphosphonic acid （OPA） to introduce hydrophobic alkyl chains on its surface so as to synthesize OPA-UiO-66/CF. The surface morphology， crystal structure， and hydrophobic & lipophilic properties of OPA-UiO-66/CF were analyzed and characterized. The results show that UiO-66 can uniformly load on the surface of CF， and the particle size of which is 1/10 of that of pure UiO-66. OPA-UiO-66/CF is of hydrophobic & lipophilic properties with separation efficiency for water-in-oil emulsions up to 99.6%. |
