俄罗斯研发出从水中吸附石油产品的新型聚合物

Core Viewpoint - Researchers from St. Petersburg University have developed a new type of fiber polymer that efficiently adsorbs oil products from water and can be reused multiple times [1] Summary by Relevant Sections Material Characteristics - The new material consists of a flexible film made of fibers with a diameter of less than 1 micron, which initiates the adsorption process when laid on the surface of oil spills [1] - The material is lightweight, elastic, waterproof, and does not sink, making it suitable for use in cold regions like the Arctic and under complex weather conditions [1] Adsorption Efficiency - The material can adsorb various types of oil products, with a maximum adsorption time of approximately two hours, and each gram of the material can adsorb about 40 grams of oil [1] - After being used for adsorption up to five times, the material retains about 80% of its initial adsorption capacity [1] Environmental Impact - According to the Russian Ministry of Natural Resources and Environment, there are approximately 10,000 oil spill incidents annually in Russia due to ship collisions, wastewater discharge, or intentional dumping, posing a threat to ecological safety [1] - This new adsorbent may become one of the methods to address such environmental disasters in the future [1]
