Preparation method of nano zero-valent iron/cellulose composite hydrogel in ionic liquid |
abstract |
The invention relates to a nano zero-valent iron/cellulose composite gel and a preparation method thereof in ionic liquid, belonging to the field of material science; the preparation method of the nano zero-valent iron/cellulose composite hydrogel in the ionic liquid comprises the following steps: (1) heating an ionic liquid to a defined temperature T 1 Then adding nano zero-valent iron at a constant temperature, stirring and ultrasonically dispersing to obtain an ionic liquid solution of nano zero-valent iron with a certain concentration; (2) heating an ionic liquid to a defined temperature T 2 Then, adding cellulose with the mass fraction of 1-10 wt% at constant temperature to prepare a cellulose ionic liquid solution; (3) stirring and mixing the nano zero-valent iron ionic liquid solution and the cellulose ionic liquid solution, and performing ultrasonic dispersion at specified temperature and power; (4) and (3) defoaming the obtained final mixed solution, regenerating by using a coagulating bath, and washing to obtain the nano zero-valent iron/cellulose composite hydrogel. |
