Abstract

Belonging to the technical field of chemistry and chemical engineering and functional materials, the invention in particular relates to a preparation method and application of a glucose coated oil-water separation membrane. The preparation method includes: adding glucose into deionized water and fully stirring the substances to obtain a glucose aqueous solution; adjusting the pH value of the glucose solution, and then putting a cellulose net membrane into the solution for soaking; then taking the cellulose net membrane out and putting it in a glutaraldehyde aqueous solution for soaking; and then taking the cellulose net membrane out, and conducting full washing and drying, thus obtaining the glucose coated oil-water separation membrane. The prepared glucose coated oil-water separation membrane can be applied to oil-water separation or oil-water emulsion separation.

Description

technical field

[0001] The invention belongs to the technical fields of chemical engineering and functional materials, and in particular relates to a preparation method and application of a glucose-coated oil-water separation membrane. Background technique

[0002] Due to the occurrence of a large number of offshore oil spills and the discharge of a large amount of oily wastewater to the environment in the production process of the food, machinery, and petrochemical industries, oil-water separation is of great significance in production and life.

[0003] In recent years, oil-water separation membrane materials based on the special wettability of the material surface have attracted much attention due to their excellent oil-water separation effect. Superhydrophilic and underwater superoleophobic films are superhydrophilic in air and superoleophobic in water. When it is used for oil-water separation, water penetrates downward under the action of gravity and capillary force, a...
