The hopcalite (CuMnOx) catalyst is a well-known catalyst for CO oxidation at a low temperature and it is synthesized by the co-precipitation method with different types of precursors. Activity of the CuMnOx catalysts for CO oxidation is strongly dependent upon the combination of precursors, ranking in order {Mn(Ac)2 + Cu(NO3)2} > {Mn(Ac)2 + Cu(Ac)2} > {Mn(NO3)2 + Cu(NO3)2} > {Mn(NO3)2 + Cu(AC)2}. All the precursors were precipitated by KMnO4 […]
This work proposes a kinetic model for the reactions involved in the heterogeneous copper-based Fenton-type oxidation of mixed recalcitrant compounds in a real industrial effluent from the alkaline sulfite treatment of wood. This kind of treatment is unusual in this industry due to the complexity of the effluents and the high costs involved in total […]
Epoxy resin (ER) is an attractive material for metal protection against corrosion; it can form a strongly adhered film onto a metal surface through its multi coordination sites. In this study, an epoxy resin-based formulation was designed, prepared, and applied onto steel surface with and without a pigment. The anticorrosive formulation (ER–MDA–ZP) was prepared from […]
The release of dye containing effluent is a great threat to the world today. The purpose of this study is to optimize the removal of Reactive Blue 19 (RB19) dye from aqueous solutions using advanced oxidation process (AOP). Magnesium oxide nanoparticles (MgO NPs) and hydrogen peroxide (H2O2) were used as the catalyst and oxidizer, respectively. […]
The inhibitive action of plant leaf extracts, Crataegus oxyacantha (Hawthorn) and Prunus Avium (Sweet Cherry) on the corrosion of mild steel in 0.5 M HCl solution was investigated using open circuit potential-time measurements (OCP), potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) techniques. Functional groups of these plants’ leaf extracts and their absorption bands were identified by […]
Wood fibers were used as fillers in the partial cement matrix by replacing the cement to a content of 1% by weight of cement. The effect of wood fibers on porosity and compressive strength has been studied. The results obtained show an improvement in the compressive strength of more than 40% with 1% by weight […]
Decolourization process of neutralized sunflower oil was carried out with activated carbon products obtained from pyrolysis liquid products. The effect of parameters such as time, temperature, moisture and dosage on bleaching sunflower oil was investigated. It was found that activated carbon samples are an effective adsorbent for decolourization process of sunflower oil. It was determined […]
In this study, removal of m-cresol has been performed using photoeletrocatalysis technique at the surface of titanium dioxide (TiO2) thin film-modified carbon sheet photoelectrode. A biased potential was applied across this photoelectrode illuminated by UV light to investigate the feasibility of an electrochemically assisted photocatalytic process in this degradation. For preparation of this photoelectrode, the […]
