Photochemistry of Polycyclic Aromatic Hydrocarbons with Environmentally Relevant Metals
… involving the photo-oxidation of PAH into humic-like substances (HULIS). Aqueous suspensions of PAH and oxidized PAH products are illuminated by a bench solar simulator and resulting samples are analyzed by high-pressure liquid chromatography (HPLC), UV-Vis, attenuated total reflectance …

Complexation state of iron and copper in ambient particulate matter and its effect on the oxidative potential
… as a model compound as it represents the humic-like substances present in ambient PM, which are believed to be complexed with Fe and Cu. The results show that a significant amount of iron pre-mixed with SRFA is detected in both hydrophobic and hydrophilic fractions, indicating potential …

Bioavailability of dissolved organic matter in coastal waters
… DOC and its rate constants from the DOM protein-like fluorescence, whereas refractory DOC could be estimated from in situ CDOM and humic-like substances in the Ría de Vigo.<br/>Heterotrophic microbes have often been viewed as the main consumers of DOM, but it is now evident that they can also …

Investigation of effect of dynamic operational conditions on membrane fouling in a membrane enhanced biological phosphorus removal process
… and, bound and soluble extracellular polymeric substances (EPS) were quantified, to evaluate their role on membrane fouling. The tests results suggest that the inflow variation in an MEBPR process did not make a significant difference in any of the measured parameters. With decreased SRT, an …
