Cobalt mediated electro-scrubbers for the degradation of gaseous perchloroethylene
(Elsevier, 2021-09)
This work focuses on the treatment of gaseous perchloroethylene (PCE) using electro-scrubbing with diamond electrodes and cobalt mediators. PCE was obtained by direct desorption from an aqueous solution containing 150 mg ...
Toward the Development of Efficient Electro-Fenton Reactors for Soil Washing Wastes through Microfluidic Cells
(ACS, 2018-07)
This work focuses on the coupling of three different approaches into the same reactor at the same time: microfluidic cells, anodic oxidation with diamond anodes, and an electro-Fenton process. To supply oxygen a jet aerator ...
Electro-Absorbers: A Comparison on Their Performance with Jet-Absorbers and Absorption Columns
(MDPI, 2020-06)
This work focuses on the removal of perchloroethylene (PCE) from gaseous streams using absorbers connected with electrolyzers. Two types of absorption devices (jet absorber and absorption column) were compared. In addition, ...
Integrating ZVI-dehalogenation into an electrolytic soil-washing cell
(Elsevier, 2019-03)
Combination into a single electrochemical reactor of soil washing, ZVI dehalogenation and anodic oxidation can be used to degrade directly the clopyralid contained in spiked soil. Treatment is efficient, achieving the ...
Improving biotreatability of hazardous effluents combining ZVI, electrolysis and photolysis
(Elsevier, 2020-04)
In this work, nine types of combination advanced oxidation processes/zero-valent iron (AOP-ZVI) were tested, in order to determine if any of these combinations demonstrate good chances as pretreatment for the biological ...
A new electrochemically-based process for the removal of perchloroethylene from gaseous effluents
(Elsevier, 2019-04)
Removal of perchloroethylene using combined granular active carbon (GAC) adsorption and electrolysis is evaluated in this research. There is an interest in the regeneration of GAC using methanol solutions, because this ...
A new strategy for the electrolytic removal of organics based on adsorption onto granular activated carbon
(Elsevier, 2018-05)
In this paper, a new strategy for the electrochemical treatment of organic pollutants is introduced. This is based on the concentration of organics by adsorption onto granular active carbon (GAC) with the consequent ...
Electrolysis with diamond anodes of the effluents of a combined soil washing – ZVI dechlorination process
(Elsevier, 2019-05)
In this work, a new soil washing process in which Soil-Liquid extraction technology is enhanced by adding iron particles (zero valent iron nanoparticles or granules) was investigated to remove clopyralid from spiked soils. ...
Improvement of electrochemical oxidation efficiency through combination with adsorption processes
(Elsevier, 2020-05)
In this work, a three-step process (adsorption-desorption-electrolysis) is evaluated as an interesting approach for the removal of organochlorinated compounds (clopyralid, lindane and perchloroethylene) with different ...
Jet electro-absorbers for the treatment of gaseous perchloroethylene wastes
(Elsevier, 2020-09)
In this work, a novel jet electro-absorber is presented as an efficient process that combines absorption and electro-oxidation for the treatment of gaseous pollutants. This system, based on the Venturi effect, enhances the ...
