In this study, we aimed to systematically optimize the operating parameters in degradation and mineralization of tetracycline by Fenton process. For purpose; optimum values were found for Fe2+ concentration, H2O2 concentration pH, reaction time, sedimentation times which are effective study where initial was used as 100 mg/L; 4 30 mg/L 10 min time 90 time. Under these conditions, TC 100%, while...

Industrial pollutants induce the production of toxic reactive oxygen species (ROS) such as O2.-, H2O2, and ·OH in plants, but they have not been well quantified or localized in tissues and cells. This study evaluated the pollutant- (HSO3-, NH4NO3, Al3+, Zn2+, and Fe2+) induced toxic effects of ROS on the aerial roots of Chinese banyan (Ficus microcarpa). Root cell viability was greatly reduced ...

Myocardial phospholipase D (PLD) is primarily localized at the sarcolemmal level and selectively hydrolyzes phosphatidylcholine to form phosphatidic acid as part of the signal transduction mechanisms for regulating Ca2+ movements in the heart. Since the myocardial cell damage induced by oxidative stress is associated with abnormalities in Ca2+ homeostasis and thiol status, we examined the thiol...

Abstract In this work, the degradation of chloranilic acid (CAA) by chemical oxidation with H 2 O alone and in presence ferrous iron Fe 2+ catalyst was investigated order to improve our understanding on novel metal-independent approach. The interesting efficient hydroxyl radicals (OH) production using halogenated quinones has been currently demonstrated. results clearly confirmed formation OH f...

In this study, the applicability of factorial design to treatment greywater (GW) containing dodecyl-benzene sulfonic acid (LAS) by electrochemical advanced oxidation processes (EAOPs) is demonstrated. At bench scale, anodic with electrogenerated H2O2 (AO-H2O2) and photoelectro Fenton (PEF) were studied following a 23 central point insertion, using first-order mathematical polynomial. former pro...

Dry leaf extracts of eastern teaberry (Gaultheria procumbens L.) were evaluated as a source of bioactive phytocompounds through systematic activity testing and phytochemical profiling. The antioxidant efficiency was tested using five complementary in vitro models (DPPH; FRAP; linoleic acid (LA) peroxidation assay; O2•- and H2O2 scavenging tests) in parallel with standard antioxidants. The 75% m...

Grey water is a kind of domestic wastewater including shower, bath, lavatory and laundry waters. waters without faecal waste can be considered as alternative sources in the place where resources are limited. In present study, removals COD, anionic non-ionic surfactants from grey via conventional (CFP) modified (MFP) Fenton oxidation processes was experienced. It determined that pH adjustment to...

The chemical decomposition of p-hydroxyphenylacetic acid, a priority phenolic pollutant present in wastewaters from some agro-industrial plants, is studied by means of a single photochemical process produced by a polychromatic UV radiation and by hydroxyl radicals generated by the combination of UV radiation plus hydrogen peroxide and by the Fenton's reagent (hydrogen peroxide plus ferrous salt...

Background: For a long time, special attention in experimental biology and medicine is paid to free radical processes involving reactive oxygen species. In electromagnetic biology, the interest oxidation biological membranes has increased significantly due discovery of spin mechanisms magnetic fields on processes. present day, these are considered be key magnetoreception living organisms. Lipos...

Three novel non-heme micro-oxo-bridged diiron(III) complexes [Fe2(micro-O)(L1)2] 2, where H2(L1) is N,N'-o-phenylenebis(salicylideneimine), [Fe2(micro-O)(L2)2].2H2O 4, where H2(L2) is N,N'-o-phenylenebis(3,5-di-tert-butylsalicylideneimine), and [Fe2(micro-O)(L3)2] 6, where H2(L3)=1,4-bis(2-hydroxybenzyl)-1,4-diazepane, have been isolated and studied as catalysts for the selective oxidative tran...
