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...

Abstract

The invention discloses a preparation method for oil and water separation filter paper for naphtha and diesel oil. The method comprises the following steps: dissolving octadecyltrichlorosilane into an n-hexane solution according to a volume ratio, dipping the filter paper into the mixing solution at room temperature, taking out the filter paper and putting the filter paper into a constant temperature drying oven to dry so as to obtain oleophilic hydrophobic filter paper. The method is simple to operate, short in manufacturing period, low in cost and less in energy consumption. The preparation method has good application prospect in application in aspects such as industrial oil and water separation and oil clearance of water.

Description

technical field [0001] The invention relates to a method for preparing oil-water separation filter paper, in particular to a method for preparing filter paper for heterogeneous gasoline and diesel oil-water separation. Background technique [0002] In recent years, water pollution caused by leakage of petroleum and various organic chemical reagents has occurred frequently and has become a global problem. Polluted water bodies usually contain harmful or toxic substances that threaten human health, so effective measures need to be taken to remove or separate oil from water bodies. There are two main traditional treatment methods: physical methods and bio-chemical methods. Because bio-chemical degradation methods may cause secondary pollution, physical extraction or separation methods are more advantageous. Therefore, research on lipophilic and hydrophobic materials for oil-water separation has attracted widespread attention. At present, some people have used carbon material...
