Comparative analysis of the results of the investigations, which were performed by means of
photon correlation spectroscopy (PCS) and electrophoresis, of aqueous suspensions of …

Quantitative characterization of the development of proton surface charge on the surfaces of
minerals is necessary for a fundamental understanding of reactions between minerals and …

The variability of quartz hazard stands as one of the most puzzling issues in particle
toxicology, notwithstanding the fact that silicosis, the most ancient occupational disease, was …

The effect of pH and redox potential on the redox equilibria of iron oxides in aqueous-based
magnetite dispersions was investigated. The ionic activities of each dissolved iron species in …

The chelate molecule, ethylenediamine, has been incorporated onto the surface of cellulose
by sequential reaction of cellulose fibres with phosphorous oxychloride followed by the …

Among the physico-chemical features responsible for the so-called “variability of quartz
hazard”, a key role has been assigned to the silica surface charge, evaluated by means of ζ …

Despite the success of surface complexation models (SCMs) to interpret the adsorptive
properties of mineral surfaces, their construct is sometimes incompatible with fundamental …

Calorimetric acid− base titration of purified aluminum oxide C (Degussa) was performed
under delicate experimental conditions. The initial state of titration was fixed at the reference …

Brazilian sawdust samples (Caryocar spp.; Manilkara spp.; and Tabebuia spp.) have been
used for Cr (VI) adsorption from water. The series of adsorption isotherms were adjusted to …

The herbicide 4-amino-3, 5, 6-trichloropicolinic acid (picloram), chemically anchored on
silica gel surface (SiPi), has been used for divalent cation M2+ (Cu, Ni, Zn, and Cd) …
