Performance of a Vapor-Fed Polybenzimidazole (PBI)-Based Direct Methanol Fuel Cell
(American Chemical Society, 2008)A high-temperature vapor-fed direct methanol fuel cell (DMFC) has been implemented using H3PO4-doped polybenzimidazole (PBI) as the electrolyte. The influence of the cell temperature, the methanol concentration, and the ... -
Conductive-Diamond Electrochemical Oxidation of Surfactant-Aided Soil-Washing Effluents
(ACS Publications, 2010)Washing of soils polluted with polycyclic aromatic hydrocarbons (PAHs) using surfactant is a widely used technique. Once the pollutant is transferred to the washing solution, the polluted wastewater has to be treated. In ... -
Influence of the Type of Surfactant on the Mobility of Flushing Fluids for Electro-Remediation Processes
(Taylor & Francis, 2011)The mobility of four flushing fluids in an electro-remediation process has been studied. A mock-up plant with two rows of three electrodes positioned in semipermeable electrolyte wells was used in this study. Two different ... -
Electro-osmotic fluxes in multi-well electro-remediation processes
(Taylor &Francis, 2011)In recent years, electrokinetic techniques on a laboratory scale have been studied but few applications have been assessed at full-scale. In this work, a mock-up plant with two rows of three electrodes positioned in ... -
Electrochemical Synthesis of Peroxyacetic Acid Using Conductive Diamond Electrodes
(ACS Publications, 2011-08-20)In this work, the synthesis of peroxyacetic acid and peroxoacetate salts by electrolysis with conductive-diamond anodes is described, using three different raw materials: ethanol, acetaldehyde, and sodium acetate. Results ... -
Costs estimation of an integrated process for the treatment of heavy-metal loaded aqueous effluents
(Springer, 2011-09)This work aims at providing a guide for the calculation of investment and operation costs of a process to treat diluted streams of heavy metal ions. This process is composed of two stages: (1) a metal concentration stage ... -
Electrokinetic transport of diesel-degrading microorganisms through soils of different textures using electric fields
(Taylor & Francis Group, 2012-01-13)The mobilisation of diesel-degrading microorganisms in soils of three different textures (sandy, clay and silty) using electrokinetic techniques was studied. The mobilisation tests were performed using a laboratory-scale ... -
The use of a combined process of surfactant-aided soil washing and coagulation for PAH-contaminated soils treatment
(Elsevier, 2012-03)Polycyclic aromatic hydrocarbons (PAHs) persist in soils due to their low volatility, low water solubility and low biodegradability, all of which make it difficult to remove this type of compound from soils. The work ... -
Electrochemical denitrificacion with chlorides using DSA and BDD anodes
(Elsevier, 2012-03)In this work, the electrochemical denitrification of solutions containing chlorides is studied with two different types of anode materials: O2-dimensionally stable anodes (DSA) and boron doped diamond (BDD). First of all, ... -
Effect of the cathode material on the removal of nitrates by electrolysis in non-chloride media
(Elsevier, 2012-04)In this work, the effect of the cathode material (conductive diamond, stainless steel, silicon carbide, graphite or lead) and the current density (150–1400 A m−2) on the removal of nitrates from aqueous solutions is studied ... -
Electrocoagulation of the effluents from surfactant-aided soil-remediation processes
(Elsevier, 2012-09)The work described here concerns the electrochemical coagulation of effluents obtained in a surfactant-aided soil-remediation processes, in which phenanthrene was extracted from a clay soil using a sodium dodecyl sulphate ... -
Modelling and cost evaluation of electro-coagulation processes for the removal of anions from water
(Elsevier, 2013)A mathematical model previously proposed by our group has been modified for its application in the modelling of arsenates, nitrates and phosphates electro-coagulation with iron and aluminium. It classifies the coagulant ... -
Mercury emissions in equilibrium: a novel approach for the quantification of mercury emissions from contaminated soils.
(2013)Mercury emissions from soil samples with different mercury contents have been estimated using a closed circuit array. The samples were collected from the Almaden mercury mining district. The emissions confirmed that ... -
Treatment of Cu/Zn wastes by combined PSU–electrodeposition processes
(Elsevier, 2013-02)This work is focused on the study of the electrodeposition stage of a combined polymer-supported ultrafiltration (PSU)–electrodeposition process for the recovery and selective separation of Cu/Zn mixtures. With this aim, ... -
Optimization of an integrated electrodisinfection/electrocoagulation process with Al bipolar electrodes for urban wastewater reclamation
(Elsevier, 2013-04)In this work, a novel integrated electrochemical process for urban wastewater regeneration is described. The electrochemical cell consists in a Boron Doped Diamond (BDD) or a Dimensionally Stable Anode (DSA) as anode, a ... -
On the applications of peroxodiphosphate produced by BDD-electrolyses
(Elsevier, 2013-11)Peroxodiphosphate can be produced efficiently by electrolyses of phosphate solutions with boron-doped diamond electrodes. This oxidant is proposed in literature as a promising alternative to persulphates and to other ... -
