There have been proposals to use medical masks, cellulose products and devices with a magnetic core as sorbents.
Chemists from Tomsk Polytechnic University, TPU, have developed a new material that effectively purifies water from oil products. It is based on polymer medical waste: medical masks and hospital sheets. The material developed by scientists has hydrophobic and oleophilic properties, high oil adsorption capacity and low cost, the Journal of Environmental Chemical Engineering publishes.
In the course of fundamental research, chemists obtained a prototype oleophilic fabric measuring up to 65 square meters. see. The sample became a prototype for the potential use of the material: a cloth is spread on top of an oil spill, and after a minute it is removed mechanically, taking with it all the oil contaminants and leaving clean water.
Ecologists from Perm Polytechnic University have developed a technology that will help effectively clean soil and water. For the first time, scientists are creating a biosorbent based on waste from pulp and paper production, according to the university’s website.
Scientists from Kuzbass State Technical University (KuzGTU) have patented magnetically controlled and floating sorbents for cleaning reservoirs from oil spills and plan to use them in the Caspian Sea to protect the world’s largest enclosed reservoir from pollution.
The oil sorbent is created on the basis of carbon-containing waste, which serves as an absorbent shell; in the center there is a magnetite core, which attracts the oil film in water bodies and allows it to be controlled for effective spill response. In the event of an emergency, Magnesorb will help quickly and effectively clean up a spill without harming the environment.
Experts believe that the world’s oceans are suffocating due to a lack of oxygen caused by global warming and ocean pollution from sewage and industrial waste. Experts believe that to save the oceans, it is necessary to solve the problems of drinking water and sanitation on land, and it is also necessary to stop the uncontrolled dumping of waste into the sea.
