Bacterial inactivation with iron citrate complex: A new source of dissolved iron in solar photo-Fenton process at near-neutral and alkaline pH
César Pulgarin, Andrzej Sienkiewicz, Cristina del Socorro Lonfat
This study reports the first application of Fe-citrate-based photo-Fenton chemistry for the inactivation of Escherichia coil. Promising results of bacterial inactivation at near-neutral and alkaline pH conditions were obtained, while using low iron concent ...
Elsevier2016Castles fall from inside: Evidence for dominant internal photo-catalytic mechanisms during treatment of Saccharomyces cerevisiae by photo-Fenton at near-neutral pH
César Pulgarin, Sami Rtimi, Stefanos Giannakis, Cristina del Socorro Lonfat
In this work, the antimicrobial effects of the photo-Fenton process on yeast cells were tested (Saccharomyces cerevisiae), an essential eukaryotic unicellular model of living cells. Near-neutral pH was used in all studies, while iron sulfate and iron citra ...
Elsevier2016Iron-oxides and iron-citrate as new photocatalysts in solar inactivation of Escherichia coli in water
This study addresses the bacterial inactivation mechanism by photo-Fenton process at near-neutral pH, focusing on iron-oxides and iron-citrate as photocatalysts for solar water disinfection and using E. coli as a bacteria model. Cell envelope damage during ...
EPFL2015Iron oxides semiconductors are efficients for solar water disinfection: A comparison with photo-Fenton processes at neutral pH
César Pulgarin, Andrzej Sienkiewicz, Michaël Bensimon, Cristina del Socorro Lonfat
The photocatalytic activities of four different commercially available iron (hydr)oxides semiconductors, i.e. hematite (alpha-Fe2O3), goethite (alpha-FeOOH), wustite (FeO) and magnetite (Fe3O4), were evaluated for bacteria inactivation at neutral pH in the ...
Elsevier2015Deleterious effect of homogeneous and heterogeneous near-neutral photo-Fenton system on Escherichia coli. Comparison with photo-catalytic action of TiO2 during cell envelope disruption
César Pulgarin, Andrzej Sienkiewicz, Cristina del Socorro Lonfat
The mechanisms underlying bacterial inactivation by solar photo-Fenton at near-neutral pH have not yet been investigated in detail. In particular, no consensus exists on the bacterial inactivation mechanism under solar light enhanced by the Fenton's reagen ...
