The formation of the nanocomposites was accompanied by the appearance of the second lepidocrocite phase. The nanocomposite particles belong to superparamagnetics and they showed the unique bioplasmonic properties that will be perspective for the bio-medical application in the future.","PeriodicalId":20682,"journal":{"name":"Proceedings of the NTUU “Igor Sikorsky KPI”.

By its protective properties, it surpasses all known materials used in protection against ionizing radiation. The article analyzes the possibility of improving the container used at the ChNPP for the storage of HLW KTZV0,2. Developed models and calculations carried with the possible addition of depleted uranium to the composite of concrete, as well as the possibility of using, instead of lead, segments of depleted uranium in containers with the addition of an additional protective layer. Calculations have shown that the use of depleted uranium in protective containers for HLW allows reducing the total number of containers. That required for temporary storage of HLW in ChNPP repositories, which makes it possible to optimize the scheme of radioactive waste management at ChNPP during the work on the decommissioning and conversion of the Shelter object on an environmentally safe system. The application of depleted uranium as an impurity to the concrete composite and the use of it as an additional metal protection in containers KTZV-0,2, considered by us, showed that:there is a decrease in the dose rate from 2 to 4 times, depending on the addition of the percentage to the concrete composite; the efficiency of the protective properties of the use of uranium is increased compared with lead in the application of depleted uranium in the form of metal plates. This allows you to increase the activity of VAB in the container to 3.95E + 18 Bq, compared with lead.","PeriodicalId":20682,"journal":{"name":"Proceedings of the NTUU “Igor Sikorsky KPI”.

The greatest interest is the purification of sewage from ions of copper (II). From the variety of available methods for purifying water from heavy metal ions, the most potentially suitable are traditional reagent methods as they are versatile, easy to operate and cheap. But they do not always provide theadmissible concentrations. All this necessitates the development and implementation of new modern technologies that allow ensuring high efficiency of the processes of purification from heavy metal ions. This also gives possibility of creating integrated technologies with a closed cycle of water consumption on their basis. Recently, the interest in derivatives of iron-synthetic acid has increased considerably; ferrocyanides acquire a rapidly growing practical value. It is known that ferrocyanides of heavy metals have very low solubility, therefore it was suggested to use potassium ferocyanide as a precipitant in order to remove copper ions from the researched solutions. Since the copper (II) ferrocyanides can form stable colloidal systems, settling solutions will be a long-term and technologically not always justifiable solution, because of its inappropriate usage as an independent method of purification. Typically, this method is combined with the filtering method. In this work, the effectiveness of the flocculantZetag 7547 was investigated. The purpose of this work is to study the features of sewage purification from copper ions (II) applying precipitation method using potassium ferrocyanide and water soluble polyelectrolyte Zetag 7547. To achieve this goal, the following tasks need to be solved: increase the depth of the deposition reaction; intensify the processes of aggregation and sedimentation of particles of the dispersed phase. To reach the optimal conditions for reagent treatment of wastewater, preliminary studies of the pH solution influence on the solubility of the formed copper (II) ferrocyanates have been made. Studies have shown that optimal pH values of precipitation of Cu (II) are within the range of 6.5 to 7.5. In order to intensify the reagent water purification, it was suggested to make its processed flocculation. When used in low concentrations, Zetag-7547 flocculant decreases potassium ferrocyanide significantly from aqueous solutions. From obtained results list of ratios of concentrations of potassium ferrocyanide and flocculant, which should be used to purify water from ions copper (II) were selected. After settling in the solution, a part of coarse dispersed impuritiesremain. They were removed by filtration, which increased the degree of purification up to 99%. Thus, in current research the processes of formation of copper (II) ferrocyanides complexes depending on the pH environment are analyzed, the conditions of reagent treatment of water usi","PeriodicalId":20682,"journal":{"name":"Proceedings of the NTUU “Igor Sikorsky KPI”.
