Adsorption Mechanism of Arsenic on Nanocrystalline Titanium Dioxide
TL;DR: The study suggests that TiO2 is an effective adsorbent for As removal due to its high surface area and the presence of high affinity surface hydroxyl groups.

Spectroscopic study of extracellular polymeric substances from Bacillus subtilis: aqueous chemistry and adsorption effects.

TL;DR: Goethite-EPS spectra show emergent vibrations consistent with P-O-Fe bonding, which suggests a role of phosphodiester groups in the adsorption reaction, and ATR-FTIR spectroscopy shows complexation and dissociation of protons on acidic functional groups that result in alpha-helical protein conformation at pH < 2.6 and random coil (unordered) conformation on higher pH (>6.

In situ Fourier-transform infrared spectroscopy studies of inorganic ions adsorption on metal oxides and hydroxides.
TL;DR: This method, characterized by an in situ analysis performed with a special cell used in a widespread instrumentation (IR spectrometer), is very recent but its advantages suitable for the current problems in the sorption field should help its rapid development for the next years.

Equilibrium and Kinetic Modelling of Adsorption of Phosphorus on Calcined Alunite
TL;DR: In this paper, the adsorption of phosphorus onto calcined alunite has been studied and its equilibrium isotherm has been measured using the Dubinin-Radushkevich equation.

Adsorption to goethite of extracellular polymeric substances from Bacillus subtilis
Anselm Omoike,Jon Chorover +1 more
TL;DR: The data indicate that both electrostatic and chemical bonding interactions contribute to selective fractionation of the EPS solution, and proteins and phosphate groups in phosphodiester bridges of nucleic acids likely play an important role in conditioning film formation at Fe oxide surfaces.

Protonation of phosphate on the surface of goethite as studied by CIR-FTIR and electrophoretic mobility
TL;DR: In this paper, the authors used CIR-FTIR, adsorption isotherm, and electrophoretic mobility data to calculate the intrinsic pK value (4.6) for the bridging bidentate iron phosphate surface complex.

Structure and Bonding of Orthophosphate Ions at the Iron Oxide-Aqueous Interface.
TL;DR: The IR data are in good agreement with a monodentate coordination of phosphate to the surfaces, where the three surface complexes only differ in the degree of protonation.
