Background: The reaction of natural organic matters (NOMs) with chlorine in the conventional disinfection process results in disinfection by-products (DBP) such as trihalomethanes and haloacetic acids. Due to the potential health risks of trihalomethanes for public health, it has attracted a lot of attention. The purpose of this study is to investigate the performance of combined Fenton-ultraso...
Backgrounds and Objectives: The base structure of total petroleum hydrocarbons (TPH) is made of hydrogen and carbon. Widespread use, improper disposal and accidental spills of this compounds lead to long term remaining of contaminations such as organic solvents and poly aromatic hydrocarbons (PAHs) in the soil and groundwater resources, resulting in critical environmental issues. In this s...
Degradation of polyvinyl alcohol was studied a combination of chemical treatment with Fenton process and biological degradation in anaerobic environment. The experiment was based on different amounts of hydrogen peroxide and of Fe(II) added to water solution of PVA of concentration 200-500 mg.L. Fenton process was monitored by analyzing the total organic carbon (TOC) in the solution. Depending ...
The mineralisation of remazol black B (RBB) was studied at concentrations ranging from 20-1000 mgL(-1). The work was aimed at investigating the Fenton-like peroxidation of RBB at a concentration typically obtained in Batik cottage industries. Other response parameters were degradation and colour removal efficiencies. The parameters that were measured included total organic carbon (TOC), chemica...
INTRODUCTION Human serum albumin (HSA) is a critical protein in human blood plasma, which can be highly damaged by oxidative stress. The aim of this study was to analyze modifications of this protein after oxidation using a Fenton system. METHODS In this 2015 experiment, different ratios of Fenton reagent (Fe2+/H2O2) was incubated with one concentration of human serum albumin (1mg/ml). Hence,...
UNLABELLED Iron and copper toxicity has been presumed to involve the formation of hydroxyl radical (*OH) from H2O2 in the Fenton reaction. The aim of this study was to verify that Fe2+-O2 and Cu+-O2 chemistry is capable of generating *OH in the quasi physiological environment of Krebs-Henseleit buffer (KH), and to compare the ability of the Fe2+-O2 system and of the Fenton system (Fe2+ + H2O2) ...
MicrosoftInternetExplorer4 Background and Objectives: Synthetic dyes represent one of the largest groups of pollutants in wastewater of dying industries. Discharging these wastewaters into receiving streams not only affects the aesthetic but also reduces photosynthetic activity. Electrochemical advanced oxidation processes such as Electro-Fenton process are low operational and have high mi...
An extensively used non-steroidal anti-inflammatory drug (NAID) diclofenac (DCF) is reported to be present in the environment. Several adverse effects have been reported due to presence of DCF and hence it should be removed from the environment. Among several treatment methods, classic Fenton oxidation is found to be an effective process for the removal of organic contaminants. In the present s...
We examined the effects of ultrasound and Fenton reagent on ultrasonic coupling Fenton oxidation (U+F) pre-treatment processes for the disintegration of wastewater treatment plant sludge. The results demonstrated that U+F treatment could significantly increase soluble chemical oxygen demand (SCOD), total organic carbon (TOC), and extracellular polymeric substances (EPS) concentrations in sludge...
