Title: Tatiana Vereshchagina: Innovator in Hazardous Waste Management
Introduction
Tatiana Vereshchagina is a prominent inventor based in Krasnoyarsk, Russia. She has made significant contributions to the field of hazardous waste management, particularly in the removal of radioactive materials from fluid waste. With a total of 4 patents to her name, her work is recognized for its innovative approaches and practical applications.
Latest Patents
Tatiana's latest patents focus on two key inventions. The first is a method for the removal of radioactive and other hazardous materials from fluid waste using hollow glass microspheres obtained from fly ash. These microspheres are impregnated with extractants and ion-exchangers, allowing for the effective removal of hazardous materials. In one embodiment, the microspheres are loaded with ammonium molybdophosphonate (AMP) to target radioactive ions like cesium-137 from acidic liquid wastes. Another embodiment utilizes octyl(phenyl)-N-N-diisobutyl-carbamoylmethylphosphine oxide (CMPO) to remove americium and plutonium from similar waste.
The second patent involves the creation of an open-cell glass crystalline porous material made from these hollow microspheres. This material boasts an open-cell porosity of up to 90 vol. % and is produced by separating the cenospheres into various fractions based on grain size, density, and other characteristics. The resulting porous material has a density of 0.3-0.6 g/cm³ and a compressive strength ranging from 1.2-3.5 MPa. It features two types of openings, making it suitable for applications such as immobilization of liquid radioactive waste, heat-resistant traps, filters, and supports for catalysts.
