В практических условиях одним из возможных решений проблемы очистки сероводородсодержащих промышленных сточных вод является электрохимическое окисление сульфидов. С учетом этих обстоятельств, в работе рассмотрена модельная система Fe–NaCl–Na2S–H2SO4–H2O, собрана экспериментальная установка и изучен процесс электрокоагуляции в широких пределах изменения температуры (288–308 К) водного раствора сероводорода. Выявлены оптимальные соотношения исходных компонентов в системе. Определены экспериментальные и расчетные водородные показатели раствора (pH). Осуществлено термодинамическое моделирование си ...Daha fazlası

Under practical conditions, one of the possible solutions to the problem of treatment of hydrogen-sulfide-containing industrial wastewater is the electrochemical oxidation of sulfides. In this work, the model system Fe-NaCl-Na2S-H2SO4-H2O is considered, an experimental setup is constructed, and the electrocoagulation process is studied in a wide (288-308 K) range of temperatures of an aqueous solution of hydrogen sulfide. The optimal ratios between the initial components in the system are determined. The experimental and calculated pH of the solution are found. The system is thermodynamically ...Daha fazlası
In this study, thermodynamic modelling of the process of thermal destruction of oil-contaminated soil of Ozenmunaigas JSC, which includes compounds such as carbon, silicon, aluminum, iron, calcium, magnesium, sodium, potassium, chromium, phosphorus, manganese, copper, titanium, molybdenum, nickel, vanadium, and water, was carried out. The physicochemical and thermodynamic parameters of the complex system were calculated at P0.1 MPa, T598-3000 K. The concentration distribution of components, particles, and condensed phases in the gas phase has been established. In the process of thermal destruc ...Daha fazlası
Interest in synthesizing functional materials from natural compounds has increased recently. For this reason, compound particles attract attention due to their multifunctional properties. Abelmoschus esculentus L. (Okra) is a vegetable species belonging to the Hibiscus family, widely used for its edible unripe fruit. This study synthesized the particle from the Abelmoschus esculentus (Okra) extract (Oe) by emulsion polymerization. In this synthesis, ammonium persulfate (APS, initiator) to form free radicals at the Abelmoschus esculentus (Okra) extract (Oe) and ethylene glycol di methacrylate t ...Daha fazlası
As oak bark extract includes pharmaceutically meaningful precious biochemicals such as vanillic acid, quercetin, catechin, caffeic acid, gallic acid, ferulic acid, syringic acid, chlorogenic acid, q-coumaric and protocatechuic acid, the present study focuses on synthesizing polymeric particles from that extract while keeping their targeted natural bioactivity. In this study, due to the bioavailability of oak bark extracts, poly(Oak bark)water extract (p(OB)w), poly(Oak bark)ethanol extract (p(OB)e) and poly(Oak bark)water-ethanol extract (p(OB)we) particles were synthesized using redox polymer ...Daha fazlası
