Embodiment Construction
[0036] The implementation of the present invention will be further described below in combination with specific examples.
[0037] The invention adopts n-hexane solution of octadecyl trichlorosilane as a hydrophobizing treatment reagent. The preparation method of oil-water separation filter paper is carried out as follows:
[0038] (1) Preparation of hydrophobization solution: Take 13 μL of Sigma’s octadecyltrichlorosilane and 10 mL of Aladdin’s n-hexane solution and mix evenly at room temperature;
[0039] (2) Modification of filter paper: Soak No.1 filter paper of Whatman Company with a diameter of 9 cm in the above-mentioned hydrophobizing solution for 5 minutes at room temperature, take it out, put it into a clean constant temperature drying oven at 40 ° C, and heat and dry it for 5 minutes. That is, hydrophobic and lipophilic filter paper is obtained;
[0040] (3) Filtration performance test of hydrophobic and lipophilic filter paper: add ultrapure water to a small amou...
