British researchers recently reported that they have developed a "magnetic soap solution" that has both the properties of a traditional liquid soap and can be attracted by an external magnetic field, which is expected to be used for marine oil cleaning and other aspects.
Soap is a surfactant, it has a special molecular chain, one easy to combine with water, and the other easily combined with oil, etc., so it can be used to remove the stain on the object. In order to obtain more versatile surfactants, researchers have been trying to make surfactants have more special properties.
Researchers at the University of Bristol and other institutions in the United Kingdom reported in a new issue of the German Journal of Applied Chemistry that they developed this “magnetic soap†by adding iron to certain chlorides and bromides. Experiments have shown that this liquid soap is placed on the bottom of a test tube and covered with a lighter liquid that is immiscible with each other. Under the application of an external magnetic field, the liquid soap overcomes gravity and resistance between different liquids. It was sucked up to the top.
Researcher Professor Julian Istow said that this study theoretically proves that "magnetic soap" can be manufactured. Although this soap is not yet ready for commercial use, it is believed that Based on this, products with a wide range of applications can be developed.
For example, in the event of a large-scale oil spill at an oil spill accident at sea, it may be possible to use "magnetic soap" to attract oil, and then use a magnet to remove the soapy liquid.
