Вивчена можливість застосування волокнистого поліамфоліту ФІБАН АК-22В як сорбенту для вилучення аніонних (кислотний червоний, прямий бордо) і катіонних (метиленовий блакитний, кристалічний фіолетовий) барвників із їх водних розчинів. Визначені оптимальні значення рН розчину і витрати поліамфоліту. Показано, що за допомогою поліамфоліту ФІБАН АК-22В можна вилучити (до 90—98 %) кислотний червоний, метиленовий блакитний, кристалічний фіолетовий і (до 56 %) прямий бордо.

The main methodological problems and strategic goals of work on creating the theory and technology of intelligent computer systems of a new generation are considered. The problems of the current state of work in the field of artificial intelligence and their causes are studied, and the need for a transition to a new generation of intelligent computer systems is substantiated. The basic principles underlying such systems, as well as the corresponding complex technology, are presented. The transition from local automation when solving particular problems to complex automation of various areas of human activity is justified. The concept of an ecosystem of interoperable intelligent computer systems is proposed, which is the basis for complex automation. The architecture of the ecosystem, the directions of its evolution, and the classes of systems included in the ecosystem are considered.

Ontology of billing system is designed, classes and relations are described. Designed model was implemented using Protégé, and was verified on the correctness and consistency.

The analysys of the problem of ensuring compatibility of computer systems was carried out. The basic principles underlying the OSTIS technology, one of the tasks of which is the solution of this problem was discussed. Special attention is paid to the principles of semantic associative computers construction, which are the hardware basis for the interpretation of systems developed on the basis of this technology.

The article is dedicated to study of the process of silver extraction out of fixing liquors by means of metal-exchange. There is shown that silver concentration in liquor is descended depending on the confusion time and mass of concentrator.

New carboxyl ion‐exchange fibers prepared by acrylic acid (AA) and N, N‐methylene‐bis‐acrylamide (MBAA) monomer grafting to polypropylene (PP) fibers based on the method of γ‐rays pre‐irradiation in air followed by a Mohr's salt redox initiation of grafting reaction were studied. Grafting degree, homopolymer quantity, monomer conversion and grafting efficiency were determined. FTIR spectroscopy was used to establish the nature of the grafted fibers. The thermal stability of the materials was investigated based on DSC analysis in N2/O2 mixture. The long‐term stability during 6–8 years of storage was examined by the measurement of the tensile strength and the elongation at break of the fibers, and the chemical oxygen demand in water extracts as well as in the oxygen uptake experiments. The influence of some factors on the useful life of the grafted fibers was studied: a MBAA cross‐linking, exposure to day light, the Fe (III) residue presence, a grafting reaction temperature. It was found that small amounts of the adsorbed Fe (III) ions increase the deterioration rate of the grafted fibers, while small amounts of MBAA delay this negative process. [ABSTRACT FROM AUTHOR]

Abstract  New nitrogen-and-phosphorus-containing fibrous ion exchangers were produced by two-stage synthesis from Nitron fiber. The ion exchangers are efficient sorbents of heavy and nonferrous metals from aqueous solutions under dynamic conditions. [ABSTRACT FROM AUTHOR]

Sorption of 90Sr on FIBAN fibrous sorbents from wastewaters is studied. The performance of sorbents depends on pH: chelating sorbent FIBAN Kh-1 efficiently sorbs 90Sr at pH 5–8, and strongly acidic sorbent FIBAN K-1, at pH 1–3. Strontium is readily desorbed from the sorbents with 2 M HCl. Conditions of sorption of strontium from various acidic wastewaters are optimized. FIBAN K-1 exhibits high sorption efficiency for 90Sr and good kinetic characteristics. With this sorbent, about 90% of radiostrontium is recovered in a convenient form from wastewaters of various compositions. [ABSTRACT FROM AUTHOR]

Treatment of drinking water to remove heavy metal ions Pb2+, Cu2+, Cd2+, Co2+, Ni2+, and Zn2+ with commercial fibrous carboxylic ion exchangers FIBAN Kh-1, K-3, K-4, and K-5 was studied. Features of metal ion sorption from two-component solutions were determined. A comparative evaluation of the sorption selectivity of FIBAN fibrous ion exchangers with respect to heavy metal ions was made. [ABSTRACT FROM AUTHOR]

The degradation products of polystyrene film specimens have been recorded and their accumulation kinetics in the presence of uniaxial tensile stresses have been studied at various temperatures. It is shown that the accumulation kinetics satisfy the Arrhenius equation for reactions in a mechanical field. The equation for the rupture life can be written in terms of the corresponding parameters of the mechanical degradation reactions. It is concluded that the rupture life and strength of polystyrene depend on the kinetics of mechanical degradation of the polymer chains. [ABSTRACT FROM AUTHOR]

The paper considers the trends in the development of artificial intelligence technologies in BSUIR for the last five years, lists the main results obtained during this period both in the field of development of artificial intelligence technologies themselves, and in the field of education in artificial intelligence and realization of interaction between teams of specialists working in this field. The necessity of transition to new-generation intelligent computer systems with a high level of interoperability and creation of an appropriate complex technology for their development, maintenance and operation is substantiated. The problems hindering the active development and implementation of new generation intelligent computer systems are considered. The concept of semantic space as a basis for representation and integration of knowledge in intelligent computer systems of new generation is considered. The principles of implementation of hardware platform for interpretation of information processes in the semantic space – associative semantic computer – are considered.
