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
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 ...More
The use of the metal free catalysts synthesized form natural and environmental friendly materials for fast generation of hydrogen is accomplished form sodium borohydride (NaBH4) methanolysis assays. Thus, green and metal free-catalysts were prepared form natural resources of ginger oil (GO). Polymeric GO particles were synthesized via emulsion polymerization technique and characterized in detail. The hydrodynamic diameters of p(GO) particles were found to be in the 220 nm and the zeta potential was - 162.48 mV. TGA results showed that thermal decomposition of microparticles was gradually conti ...More
