Adsorption onto iron oxides can enhance the removal of waterborne viruses in constructed wetlands and soils. If reversible adsorption is not coupled with inactivation, however, infective viruses may be released when changes in solution conditions cause des ...
As part of a larger study of the reactivity and mobility of uranyl (U(VI) O-2(2+)) cations in subsurface environments containing natural organic matter (NOM) and hydrous ferric oxides, we have examined the effect of reference humic and fulvic substances on ...
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 ...
Zeolites are one class of porous materials that are currently being explored for sepn. applications in the aim of reducing environmentally harmful carbon dioxide (CO2) from the combustion of fossil fuels. The several archetypical zeolites being employed or ...
Because they can host significant amounts of Co, the Mn-oxides are commonly considered as the major Co-bearing mineral species in lateritic environments. However, little is known about the process leading to the formation and/or the weathering of these Co- ...
Advanced oxidation processes (AOPs) have emerged as a promising alternative to conventional disinfection methods to control microbial water quality, yet little is known about the fate of viruses in such processes. In this study, we investigated the fate of ...
Microorganisms catalyze many of the redox transformations driving the iron cycle in the geosphere. For instance, iron cycling includes the reduction of solid-phase and soluble ferric iron (Fe(III)) to ferrous iron (Fe(II)). However, in order to reduce soli ...
It has long been hypothesized that acids formed from anthropogenic pollutants and natural emissions dissolve iron (Fe) in airborne particles, enhancing the supply of bioavailable Fe to the oceans. However, field observations have yet to provide indisputabl ...

Human enteric viruses in water sources cause a great public health risk. Conventional disinfection treatments are not able to completely inactive viruses. However, advanced oxidation processes (AOPs) have recently been shown to effectively inactivate patho ...
Stromatolites have been extensively used as indicators of ancient life on Earth. Although much work has been done on modern stromatolites, the extent to which biological processes control their structure, and the respective contributions of biological and ...
