specific Embodiment approach 1

[0021] Specific embodiment one: technical scheme of the present invention carries out according to the following steps:

[0022] 1. Preparation of oil-water mixture: the oil-water mixture includes oil / water two-phase mixture, oil / water / oil three-phase mixture or water-in-oil emulsion mixture;

[0023] 2. Put one end of the rush into the oil-water mixture prepared in step 1, and put the other end into the collector to collect the separated oil phase.

specific Embodiment approach 2

[0024] Specific embodiment two: the difference between this embodiment and specific embodiment one is that the oil described in step one is polydimethylsiloxane, n-hexane, n-octane, n-heptane, n-dodecane, toluene , Dichloromethane, Trichloromethane and Tetrachloromethane. Other steps and parameters are the same as in the first embodiment.

specific Embodiment approach 3

[0025] Embodiment 3: The difference between this embodiment and Embodiment 1 is that the oil / water mixture described in step 1 will form two types according to the density of the oil phase: the oil phase is above the water phase or the oil phase is below the water phase. oil / water mixture. Other steps and parameters are the same as in the first embodiment.

Abstract

The invention relates to an application method of juncus roemerianus, in particular to an application of juncus roemerianus in the oil-water separation process, and aims at solving the problems that a commonly-prepared intelligent response type material needs to change wettability with the help of external stimulation or other filtering devices, and automatic continuous separation of oil-water mixtures cannot be achieved without the help of external force. According to the technical scheme, the application is carried out through the following steps that 1, juncus roemerianus is treated before being used; 2, the oil-water mixtures are prepared; 3, one end of treated juncus roemerianus is placed in the oil-water mixtures prepared in the step 2, and the other end of treated juncus roemerianus is placed in a collector. Automatic continuous separation of the oil-water mixtures can be achieved without the help of external force, operation is easy, cost is reduced, and the application of juncus roemerianus in the oil-water separation field is facilitated. Juncus roemerianus is mainly applied to separation of oil and water, oil, water and oil and other two phases or three phases and separation of multiple kinds of water-in-oil emulsion.

Description

technical field [0001] The invention relates to an application method of rushes, in particular to the application in oil-water separation. Background technique [0002] Efficient separation of oil-water mixtures, especially the separation of oil-water emulsions, is of great significance in the petroleum industry, chemical engineering and environmental protection. In the past few decades, people have achieved high-efficiency separation of oil-water mixtures by preparing superhydrophobic or underwater superoleophobic materials. The separation methods are mainly adsorption or filtration. [0003] However, superhydrophobic or superoleophilic materials alone cannot effectively separate different types of oil-water mixtures. Therefore, researchers have achieved the separation of different types of oil-water mixtures by preparing smart responsive materials. The wettability of smart responsive materials can be changed by light, pH and temperature, etc. When the material wettabilit...
