Концентрационное распределение молекул и частиц в модельной системе: Fe–NaCl–Na2S–H2SO4–H2O при различных температурах процесса электрокоагуляции

Zarlık MAYMEKOV | Canarbek İZAKOV | Nurzat ŞAYKİYEVA | Mustafa DOLAZ | Mehmet KOBYA

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 ...More

Concentration Distribution of Molecules and Other Species in the Model System Fe-NaCl-Na2S-H2SO4-H2O at Various Temperatures of the Electrocoagulation Process

Zarlık MAYMEKOV | Canarbek İZAKOV | Nurzat ŞAYKİYEVA | Mustafa DOLAZ | Mehmet KOBYA

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 ...More

Electrochemical Sulfur Removal at Controlled and Uncontrolled pHs with an Iron Anode

Nurzat ŞAYKİYEVA | Mustafa DOLAZ | Zarlık MAYMEKOV | Mehmet KOBYA

In this study, sulfide removal was carried out in the Electrocoagulation process under controlled and uncontrolled pH conditions. Under optimum conditions, electrocoagulation took place in less than 40 minutes at uncontrolled pH and less than 30 minutes at controlled pH to reduce the sulfite concentration of the effluent below 0.5 mg/L. The reaction rate constant and iron-sulfide molar ratio for sulfide removal were 14.09 x 10(-2) min(-1) and 0.97 mol/mol, respectively; under uncontrolled pH conditions, they were 22.88 x 10(-2) and 0.97 mol/mol at controlled pH. The mg sulfide removed per g Fe ...More
