Item Вплив війни на ґрунти України(Сумський державний університет, 2025) Сумцова, К.С.; Яхненко, Олена Миколаївна; Yakhnenko, Olena MykolaivnaЕфективність і швидкість відновлення залежатиме як від інтеграції наукових методів у державні програми відновлення, так і міжнародної підтримки. Подолання наслідків воєнного впливу на ґрунти – ключовий етап відбудови екологічної стійкості України.Item Phosphogypsum Recycling: A Review of Environmental Issues, Current Trends, and Prospects(MDPI, 2021) Черниш, Єлізавета Юріївна; Черныш, Елизавета Юрьевна; Chernysh, Yelyzaveta Yuriivna; Яхненко, Олена Миколаївна; Яхненко, Елена Николаевна; Yakhnenko, Olena Mykolaivna; Чубур, Вікторія Сергіївна; Чубур, Виктория Сергеевна; Chubur, Viktoriia Serhiivna; Roubík, H.The problem of recycling and storage of phosphogypsum is topical for many countries around the world, as it is associated with environmental problems of pollution of water bodies, land, and atmosphere. Therefore, this paper analyzes the directions of phosphogypsum recycling and possible alternatives to its use. The main disadvantages of the existing methods of phosphogypsum processing were identified and trends in this waste management were also considered. Through the VOSviewer programme, a visualization of cluster interconnections was carried out in research publications of various fields of phosphogypsum utilization. Five clusters were formed: a red cluster—phosphogypsum recycling in the construction industry; green cluster—radiation pollution problem of phosphogypsum and phosphate fertilizers; yellow cluster—monitoring migration of phosphogypsum components in the ecosystem, with the mobile forms of heavy metals and their inflow into aquifers from phosphogypsum dumps; blue cluster—use of phosphogypsum in agriculture as an ameliorant and a component of fertilizer; and a purple cluster—the impact of phosphogypsum on microorganisms, particularly in bioremediation processes. Under the proposed integrated biochemical approach, the use of various bioprocesses of phosphogypsum recovery from waste dumps and implementation of new biotechnological solutions for processing phosphorus raw materials are presented.Item Study of the Magnetic Water Treatment Mechanism(Bentus, 2020) Васькіна, Ірина Валеріївна; Васькина, Ирина Валерьевна; Vaskina, Iryna Valeriivna; Рой, Ігор Олександрович; Рой, Игорь Александрович; Roi, Ihor Oleksandrovych; Пляцук, Леонід Дмитрович; Пляцук, Леонид Дмитриевич; Pliatsuk, Leonid Dmytrovych; Васькін, Роман Анатолійович; Васькин, Роман Анатольевич; Vaskin, Roman Anatoliiovych; Яхненко, Олена Миколаївна; Яхненко, Елена Николаевна; Yakhnenko, Olena MykolaivnaThe main problem of widespread introduction of magnetic water treatment (MWT) in the processes of water and wastewater treatment is the lack of modern research aimed at studying the mechanisms of MWT effects, in particular the influence on the physicochemical properties of aqueous solutions. This study explains the effect of MWT taking into account the physical and chemical properties of aqueous solutions due to the presence of the quantum differences in water molecules. All the MWT effects are related to the change in the physicochemical properties of aqueous solutions. It is due to the presence of two types of water molecule isomers and their librational oscillations. The result of MWT is a violation of the synchronism of para-isomers vibrations, with the subsequent destruction of ice-like structures due to the receiving of energy from collisions with other water molecules (ortho-isomers). One of the most important MWT effects includes the change in the nature and speed of the physicochemical processes in aqueous solutions by increasing the number of more physically and chemically active ortho-isomers. The MWT parameters specified in the work allow explaining the nature of most MWT effects and require developing the scientific and methodological principles for the implementation of the MWT process and mathematical modeling of the MWT process in the water and wastewater treatment. It can be used in the design of the MWT devices taking into account the constructive and mode parameters of MWT devices.
