Herein, mixed–metal nanocomposite catalysts with various compositions (CoFe2O4/xFe2O3; x = 0, 0.25, 0.50, 0.75 and 1) were successfully fabricated by a co–precipitation method. The composition morphology of the catalyst systematically characterized. highest Co content (CoFe2O4), exhibited greatest efficiency for acid orange 7 (AO7) degradation via peroxymonosulfate (PMS) activation. effects sev...

The presence of antibiotic sulfadiazine (SFD) poses threats to the ecosystem and human health, traditional wastewater treatment processes are not ideal for removal. Therefore, it is urgent develop with high efficiency targeting sulfadiazine. This study investigated degradation mineralization mechanisms SFD by ozone-based catalysis including ozone/persulfate (PS) ozone/peroxymonosulfate (PMS). d...

In this work, an RVC electrode coated with magnetic iron oxide nanoparticles was used for the degradation of methylene blue as a model dye. The electrofenton process carried out by reduction oxygen dissolved in electrolyte on modified to produce hydrogen peroxide. presence magnetite/maghemite structure produces formation OH∙ radicals that oxidize blue. RVC/coated prepared two different methodol...

Ganitri leaves (Elaeocarpus ganitrus Roxb.) contain flavonoid compounds that function as antioxidants. Antioxidants in cosmetics are used to prevent skin damage due exposure free radicals. Facial Wash is a cosmetic preparation help remove dead cells, rejuvenate the skin, dirt, oil and provide moisture. This study aims obtain facial wash formula has good characteristics effective an antioxidant ...

In this study, antioxidant activities of water-soluble protein extracts from chickpeas and white beans were investigated. The area under the curve (AUC) values of lyophilized crude protein extracts (dialyzed or undialyzed) from thermally processed (121 C for 20 min) or heat-treated (90 C for 20 min) chickpeas (73–91 lmol trolox/g) and white beans (39–67 lmol trolox/g) indicated a higher free ra...

Eucalyptus species are well reputed for their traditional use in Asia as well as in other parts of the world; therefore, the present study was designed to investigate the antimicrobial and antioxidant activities associated with essential oils from different Eucalyptus species. Essential oils from the leaves of six Eucalyptus species, including: Eucalyptus woodwardi, Eucalyptus stricklandii, Euc...

Most biological molecules exhibit more than one function. In particular, many molecules have the ability to directly/indirectly scavenge free radicals and thus act in living organisms as antioxidant. During oxidative stress, the increase of these molecules levels seems to be a biological response that in synergism with the other antioxidant defence systems may protect cells from oxidation. Amon...

alkali and alkaline earth metals hydrogen sulfate catalyzed the one-pot three component condensation reactions of aldehydes, 1,3-dicarbonyl compounds and urea or thiourea under solvent-free conditions leading to 3,4-dihydropyrimidin-2(1h)-ones in high yields at 80 °c. our results showed that biginelli reaction not only is ph dependent, but the cation of catalyst plays an important role.

In this study, the degradation of diclofenac (DCF) in a 3D electrochemical reactor was evaluated. Several parameters were studied including configuration: fluidized bed (FB), anodic packed (APB) and cathodic (CPB); type pseudo third electrode material : granular activated carbon (GAC) expanded graphite (GEG). The configuration that showed highest total organic (TOC) removal APB, with values up ...

The chemical degradation of perfluorooctanoic acid (PFOA), an –environmentally persistent contaminant, has recently attracted much attention. Still, very few reports have focused on the PFOA in soil due to process’s non-liquid, complex system and uneasy operation. In this study, thermal treatment was applied remediation contaminated soil. Complementary activation peroxymonosulfate (PMS), fresh ...
