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 ...
