Water pollution, particularly from organic contaminants like dyes, is a pressing issue, prompting exploration into advanced oxidation processes (AOPs) as potential solutions. This study focuses on synthesizing Cu
Abstract BACKGROUND Electrochemical advanced oxidation processes (EAOPs), particularly those based on either cathodic electrogeneration of H 2 O or anodic (AO) via • OH, have become attractive technological options for the complete detoxification wastewaters. Their integration with separation pre‐treatment such as ultrafiltration (UF), nanofiltration (NF) reverse osmosis (RO) may be a plausible way to reduce processing time and costs. RESULTS Raw effluents from acid alkaline elemental...
The in-situ generation of strong oxidants, such as hydroxyl radicals (•OH), persulfates and/or active chlorine species, which react with organics up to conversion into CO2, H2O and inorganic ions, depends on the nature electrode surface; their applicability have currently received great attention for remediation toxic biorefractory organic pollutants. Therefore, effect four electrocatalytic materials (Boron doped diamond (BDD), PbO2, Ti/Ru0.3Ti0.7O2 Ti/Pt) electro-oxidation industrial...
Heterogeneous photocatalysis under visible light irradiation allows performing of selective oxofunctionalization hydrocarbons at ambient temperature and pressure, using molecular oxygen as a sacrificial reagent potential use sunlight sustainable low-cost energy source. In the present work, photocatalytic material based on heterojunction titanium dioxide bismuth oxyiodide was used photocatalyst cyclohexane benzyl alcohol. The oxidation reactions were performed in homemade photoreactor...
Eucalyptus globulus wood chips were decayed by the lignin-degrading fungus Ceriporiopsis subvermispora as a pretreatment step before kraft pulping. Weight and component losses of after biotreatment following: weight (5%), glucans (1.5%), xylans (4.3%), lignin (5.7%) extractives (57.5%). The residual amount (expressed kappa number) in pulps from biotreated was lower than that undecayed control. Depending on delignification degree, biopulps presented similar or up to 4% increase pulp yield 20%...
TiC thin films were grown on 304 stainless steel substrates using the cathodic arc discharge (CAD) technique. Titanium (6N) was placed in electrode and substrate anode, besides this is a furnace. The temperature varied between 50 250 °C with increases of °C. For producing discharge, critical damping RLC (C=0.54 mF, L=2.3 mH R=0.46 mΩ) circuit employed. To grow films, methane used at pressure 3 mbar voltage 270 V. X-ray diffraction (XRD) showed TiC-phase broad peaks low intensities, however,...
Secondary Treatment Effluents (STE) from Kraft mill effluents are discharged into aquatic ecosystems with high color and chronic toxicity contents owing to the recalcitrance of compounds in effluents. The goal study was evaluate chemical precipitation, UV/H2O2, Fenton processes (H2O2/Fe2+) for oxygen demand (COD) removing STE. A circumscribed central composite model a response surface methodology were used effects variables such as Al2(SO4)3, Fe(II), H2O2 concentration pH range each...
Abstract Experimental results of electrochemical treatment acid filtrate effluents from the first ClO
Abstract This paper reports experimental results on the use of electrochemical oxidation to reduce organic load in ultrafiltration permeates from cellulose bleaching effluents. Alkaline and acid effluents industrial production ECF bleached kraft pinewood, were treated by at 20 kDa, 10 kDa 1 using a laboratory scale high performance UF unit. Electrochemical treatment permeate was conducted dual cell electro-reactor, featuring stainless steel cathode, graphite, DSA-RuO2 DSA-Pt anodes....
INTRODUCTION: Although clear guidelines for breast cancer management have been developed and widespread, there are many variations between centers even among surgeons, with impact in clinical outcomes. Use of quality indicators to assess surgical care allows comparison standards other monitoring changes post intervention. OBJECTIVE: To apply surgery evaluate usefulness. MATERIAL AND METHODS: Selected obtained from EUSOMA 2008 workshop were applied 100 consecutive treatment patients Hospital...
