Sorption models in cyclodextrin polymers: Langmuir, Freundlich, and a dual-mode approach.
TL;DR: The classic Langmuir and Freundlich sorption models and a dual-mode approach have been tested to study the sorption of aromatic molecules onto beta-cyclodextrin polymers as well as onto analogous sucrose polymers, obtained using the same crosslinking agents.
Journal ArticleDOI
Removal characteristics and mechanism of antibiotics using constructed wetlands
TL;DR: There was an inverse correlation between the occurrence and removal of antibiotics and the levels of antibiotics in the effluents of the CWs, ranging from 47.98 to 6834.66 μg/L.

Electrospray ionization mass spectrometry of terrestrial humic substances and their size fractions.
Alessandro Piccolo,M. Spiteller +1 more
TL;DR: The results show that ESI-MS is reasonably applicable to humic substances only after an extensive reduction of their chemical complexity, and it is suggested that the dominance of hydrophobic compounds in humic supramolecular associations may inhibit the electrospray ionization ofhydrophilic components.

Effect of Soil Type on Electrokinetic Removal of Phenanthrene Using Surfactants and Cosolvents
TL;DR: In this article, the effects of two different low-permeability soils, i.e., kaolin and glacial till, on electrokinetically enhanced flushing were evaluated in three bench-scale electrokinetic experiments, where each test employed a different flushing solution, deionized water, a surfactant or a cosolvent.

Cysteine-mediated electron transfer in syntrophic acetate oxidation by cocultures of Geobacter sulfurreducens and Wolinella succinogenes.
TL;DR: L-cysteine, which was provided as a reducing agent, was found to mediate the electron transfer between the two partners, and added cysteine was rapidly oxidized by the coculture during growth, but the formed cystine was not entirely rereduced even under acceptor-limited conditions.
