The kinetic and thermodynamic parameters of the decomposition of an inorganic wastewater pollutant such as potassium hexacyanoferrate (III) (PHCF) in the presence of composite catalysts based on polymer track membranes (TeMs) and copper nanoparticles (NPs) was studied. Composite catalysts were prepared by electroless template synthesis using a nontoxic reducing agent - ascorbic acid. A systematic study of the process of electroless plating of copper NPs was carried out depending on pH, deposition time, and the number of activations of the polymer template. The structure of the porous composite catalysts was investigated by scanning electron microscopy and X-ray diffractometry. The catalytic properties of the obtained composites were examined in the temperature range of 10-25 °C for a series of samples synthesized with different deposition times. It was shown that the kinetics of the decomposition reaction of PHCF corresponds to the pseudo first-order reaction. Such thermodynamic characteristics as energy, entropy and enthalpy of activation are calculated. The stability of the properties of catalysts has been studied.

Увеличение нефтеотдачи с использованием амфифильных полимеров,как успешно применяемое на всех месторождениях, ограничивается специфическимиколлекторными показателями, физико-химическими свойствами, поверхностно-дисперснымихарактеристиками пласта. Наряду с этим высокая плотность, вязкость, парафинистость, сповышенным содержанием серы, исключают преимущество какого-либо метода воздействия.В работе предпринята попытка на основе качественного изучения как самих поверхностныхсил пласта, так и качественного анализа водно-нефтяной системы исследовать, в присутствиисопутствующих компонентов, способных влиять на их физико-химические свойства,воздействие полимеров в системе "нефть-вода"

This article examines the nature of current oil recovery and knowledge of residualoil types, which is especially important when developing and introducing new ways to increase oilrecovery. In this regard, the geological characteristics, features of natural reservoirs, heterogeneity ofreservoirs and properties of oil from some fields have been studied. Physical and chemical indicatorsof oil were investigated, as well as samples of produced water from the Kokzhide deposit wereanalyzed for further research on the possibility of using polymers for enhanced oil recovery
