Enhancing the photo-Fenton treatment of contaminated water by use of ultrasound and iron-complexing agents

Stefanos Papoutsakis

The photo-Fenton process is a promising emerging technology for the treatment of contaminated water streams. It is based on the generation of reactive oxygen species that are capable of destroying recalcitrant contaminants otherwise unaffected by conventio ...

Influences of Dilute Organic Adsorbates on the Hydration of Low-Surface-Area Silicates

David Lyndon Emsley, Aaron James Rossini, Bradley Floyd Chmelka, David Benjamin Roger Antoine Gajan

Competitive adsorption of dilute quantities of certain organic molecules and water at silicate surfaces strongly influence the rates of silicate dissolution, hydration, and crystallization. Here, we determine the molecular-level structures, compositions, a ...

Understanding what limits biological phosphorus removal at Uster’s wastewater treatment plant

This study aims at better understanding what limits the biological phosphate removal at Uster’s wastewater treatment plant (WWTP). Two hypotheses were proposed to explain the limited biological phosphate removal observed at Uster’s WWTP: (i) A heterogeneou ...

The herbicide glyphosate and its metabolite AMPA in the Lavaux vineyard area, western Switzerland: proof of widespread export to surface waters. Part I: Method validation in different water matrices

Dominique Grandjean, Luiz Felippe De Alencastro

An analytical method for the quantification of the widely used herbicide, glyphosate, its main by-product, aminomethylphosphonic acid (AMPA) and the herbicide glufosinate at trace level was developed and tested in different aqueous matrices. Their derivati ...
