Abstract

The invention discloses a preparation method and application of super-hydrophobic foam iron. The preparation method comprises the following steps: firstly, electro-depositing a high-entropy alloy on super-hydrophilic foam iron, then carrying out super-hydrophobic surface treatment to obtain super-hydrophobic foam iron, and then applying the super-hydrophobic foam iron to a designed oil-water separation device to carry out oil-water separation. The method is simple in preparation process, low in production cost, green, efficient and suitable for large-scale industrial production. The prepared super-hydrophobic foam iron has the characteristics of self-cleaning, pollution prevention, long-term corrosion resistance, high oil-water separation efficiency and the like, the static contact angle of the super-hydrophobic foam iron is larger than 150 degrees, and the rolling angle of the super-hydrophobic foam iron is smaller than 10 degrees. The designed oil-water separation device can realizecontinuous oil-water separation and is suitable for oil-water separation of light oil and heavy oil, and has high separation efficiency in the separation process.

Description

technical field [0001] The invention relates to a preparation method and application of superhydrophobic iron foam, and belongs to the technical field of metal surface coating treatment. Background technique [0002] In recent years, the rapid development of the offshore oil industry and the frequent occurrence of oil spill accidents have aroused people's great concern and concern. The risk of oil spills highlights the need to develop simple and effective techniques to remove oil from spill sites. Large-scale oil spills, in addition to the direct threat to marine species and their ecosystems, this disaster and its resulting economic consequences may last for more than a decade. When an oil spill occurs, the oil seal boom is usually used to prevent the spread of oil spills and to carry out subsequent cleaning measures. Examples include oil skimmers, in situ combustion, oil absorbing materials, etc. However, most oil skimmers are inefficient at cleaning and recover mostly a...
