Contaminant co-precipitation with continuously generated and transformed iron corrosion products has received relatively little attention in comparison to other possible removal mechanisms (adsorption, oxidation, precipitation) in Fe/H2O systems at near neutral pH values. A primary reason for this is that the use of elemental iron (Fe0) in environmental remediation is based on the thermodynamic...

Considering their high abundance in the earth, iron-based materials have occasionally been regarded as promising electrode for supercapacitors. However, monometallic electrodes still demonstrate an insufficient specific capacitance value comparison to Mn-, Ni-, and Co-based compounds combined materials. Herein, enhanced heterostructure of Fe3O4@Fe2P was prepared via situ phosphorization Fe3O4. ...

This study investigated the efficiency of electerocoagulation (EC) in removing color from synthetic and simulated textile wastewater. The study on decolorization of mixed dyes is a step toward an effective treatment of textile wastewater. Two representative reactive dye molecules were selected for the synthetic dye wastewater, a blue dye alone and mixed dye (black, blue, red, 1:1:1v/v). The EC ...

in this research, the influence of chemical composition of slags and the melting rate on the impurity of commercial grade iron in esr processing has been investigated.the chemical composition and microstructure studies were evaluated, using spectrophotometer,omand edx analyses attached to sem.the results show that esr process has successfully reduced the amount and size of inclusions. in some c...

Abstract Synthesis of ferrate using NaOCl and Fe(OH) 3 from electrolysis used iron, its application for metanil yellow degradation had been done. The was conducted iron zink plates at anode cathode electrodes, respectively, Na 2 SO 4 electrolyte. dissolved ion the then made alkaline NaOH pellet soaked to solution form (FeO -). it compared with other oxidators such as permananate, hydrogen perox...

two poly(oxyethylene) derivatives 1.10-bis(2'-benzoic acid)-1,4,7,1-tetradecane (l1) and 1,7-bis(2'-benzoic acid)-1,4,7-trioxaheptane (l2) were used as suitable ionophores for the preparation of potassium-selective pvc-membrane electrodes. the resulting electrodes based on l1 and l2 exhibit linear responses to the activity of k+ ions within the concentration ranges of 3.1´10-5 -2.7´10-2 m and 2...

the electrocatalytic degradation of methyl orange (mo) on pbo2-tio2 nanocomposite electrodes was studied by cyclic voltammetry and bulk electrolysis. the results reveal that pbo2-tio2 nanocomposite electrodes possess higher oxygen evolution overpotential than pbo2 electrodes and the electrocatalytic degradation of mo on the electrodes is direct oxidation process. the influence of experimental p...

Growth in three-electrode electrochemical cells allows quantitative analysis of mechanisms involved in electron flow from dissimilatory metal reducing bacteria to insoluble electron acceptors. In these systems, gold electrodes are a desirable surface to study the electrophysiology of extracellular respiration, yet previous research has shown that certain Shewanella species are unable to form pr...

This paper reviews the development, design and applications of electrochemical technologies in water and wastewater treatment. Particular focus was given to electrodeposition, electrocoagulation (EC), electroflotation (EF) and electrooxidation. Over 300 related publications were reviewed with 221 cited or analyzed. Electrodeposition is effective in recover heavy metals from wastewater streams. ...
