| description | The invention relates to the field of oil-water separation, in particular to a method for preparing an oil-water separation adsorption material by modifying waste masks or industrial non-woven fabrics. The method includes the following steps that waste masks are disinfected and then dried for use; soaking the disinfected mask in a sodium hydroxide ethanol solution, and then washing and drying the mask; the preparation method comprises the following steps: preparing a solution 1 containing tetraethoxysilane, n-butyl alcohol, deionized water and ammonia water; putting the dried mask into the solution 1, and stirring for pre-modification to obtain a pre-modified mask; preparing a solution 2 of octadecyl trichlorosilane; putting the pre-modified mask into the solution 2, and stirring to obtain a completely modified mask; and taking out the completely modified mask, and drying to obtain the adsorption material for oil-water separation. The preparation technology is simple, the cost is low, the repeated utilization |
