Distinctive IR-Spectroscopic Features of Functional Groups of Low-Grade Phosphorites After Microbiological and Acid Processing
Get PDFThe article discusses the current problems of enrichment of low-grade phosphorites by the thermal method as well as the production of mineral fertilizers using various acids. An alternative biotechnological method for producing organomineral fertilizers using neutrophilic, heterotrophic microorganisms of activated sludge at a biochemical treatment station for municipal wastewater for the processing of low-grade phosphorites and the production of phosphorus-containing organomineral fertilizers is proposed.In this case, a natural acceleration of the processes of the phosphorus cycle in nature occurs, which does not pollute the environment. A comparative description of IR spectroscopic descriptions of the results of microbiological treatment and treatment with sulfuric and nitric acids showed distinctive characteristics of the appearance of functional groups, which showed the transfer of valuable phosphorus components during acid treatment to sediment and their irrevocable loss in the form of waste.The studies will serve the utilization of low-grade phosphorites unused in the production, the production of a new type of organomineral fertilizer using and recycling of human waste (in most countries, incinerated), will lead to a gradual improvement in the structural composition of soils.Human vital activity waste and low-grade phosphorites have zero cost, the applied technology of biochemical treatment of domestic wastewater is available in all major cities that can be used to enrich phosphorites with organic matter

Use Of Interactive Methods of Physicall Education Teachers
Get PDFThe purpose of the article is to substantiate cyclical matrix of the use of interactive teaching methods in the process of training future teachers physical culture. The article is devoted to the current problem of modernizing the professional training of future teachers of physical culture. Own observations and special studies in this regard indicate the need to systematize and implement interactive teaching methods. The author of the article reveals the possibilities of using case situations, sketch projects, research and heuristic games and functional trainings on the basic disciplines of the curriculum special attention in the work is paid to the activity approach, intensification and optimization of the training of future teachers physical culture, expansion of interdisciplinary connection
The Role of Medium Condition for Uranium Separation from Central Kyzylkum’s Low-grade Phosphorite after Sulfuric Acid Treatment
Get PDFThis article presents the results of separating radioactive elements, particularly uranium, from low-grade phosphorites of the Central Kyzylkum by low concentrated sulfuric acid solution, which is practically feasible at the Kyzylkum phosphorite combine (KPC). In world practice, uranium was extracted from phosphorite ore in the countries of the Middle East (Syria, Morocco, Algeria, Egypt) at the final stages of obtaining phosphorus fertilizers at metallurgical and chemical plants. The extraction of uranium from phosphorite ore is not practiced in Uzbekistan. The proposed method is fundamentally different from the above and is recommended to be applied at the initial stage of enrichment phosphorite ores in the enrichment plants. Studies have shown that the uranium completely passed into solution by treating phosphorite ore with weak concentrated sulfuric acid solution. Analyses of solution and sediment composition showed that the useful component, P2O5, remained in the sediment, increasing from 8.69% to 10.3%, while uranium passed into the solution with alkaline salts alkaline-earth elements. To obtain a finished product, the resulting enriched solution was added to the richer phosphorite ore. When performing the above processes, the pH of the medium was kept at the neutral level, which is of great practical importance for the implementation of this method with minimal economic costs using conventional inventory, corrosion resistance, and environmentally friendly phosphorus fertilizer
