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 ...Более

The Impact of Road Salts on Groundwater and Estimation of the Chlorine Ions by Hydrogen Index

Canarbek İZAKOV | Kubat KEMELOV | Nurzat ŞAYKİYEVA | Zarlık MAYMEKOV

In this study, the influence of road salts on groundwater was investigated. The use of anti-ice reagents in winter requires certain precautions since the main chemical composition of the salts is chlorides. At the same time, the widely used sodium chloride does not form ion pairs in water, which means that it has a high migration ability and a weak sorption potential. In addition, the concentration of chloride salts in the components of the environment is so high (10-140 ppm). Therefore, the rapid assessment of the concentration of technogenic chlorine ion in water by pH is an urgent task. The ...Более
