Adsorption of Phenanthrene by Stevensite and Sepiolite [PDF]
Clay Minerals, 2017 AbstractPolycyclic aromatic hydrocarbons are increasingly widespread pollutants introduced into the environment via oil spillage and incomplete anthropogenic combustion of fossil fuels. In this work, the capacity of stevensite and sepiolite to adsorb phenanthrene (PHE) has been evaluated experimentally by batch testing.

A New Ni-Rich Stevensite From the Ophiolite Complex of Othrys, Central Greece [PDF]
Clays and Clay Minerals, 2006 AbstractThe first occurrence of Ni-rich stevensite found in the ophiolite complex of Othrys, Central Greece is described. The stevensite, which develops in cracks in a host serpentinite, formed at the expense of serpentine. Two varieties of stevensite have been described: a Mg-rich, Ni-poorer variety with 0.4–1.2 octahedral Ni atoms per half formula ...

Biogeofilter With Hydrothermal Treated Stevensite Clay and Laccase Enzymes for Retention and Degradation of Tetracycline [PDF]
Minerals (Basel, Switzerland), 2022 The concentration of antibiotics in surface water is an issue of high concern. The present study aims to manufacture and evaluate a biogeofilter, with stevensite clay and enzymes immobilized on it, for the adsorption and degradation of tetracycline-based antibiotics.

Stevensite-Based Geofilter for the Retention of Tetracycline From Water [PDF]
Science of the Total Environment, 2018 The antibiotic tetracycline, is considered a contaminant of emerging concern due to its presence in wastewater effluents, surface waters and groundwaters. Adsorption of tetracycline on soils and clays has been extensively studied to remove the contaminant from the water. A decreasing adsorption as the pH increases is normally reported in the pH range 3-

Correlation Between Eletrokinetic Mobility and Ionic Dyes Adsorption of Moroccan Stevensite [PDF]
Applied Clay Science, 2010 This study aims at establishing a correlation between the electrical charge of Moroccan stevensite particles and ionic dyes adsorption. The electrophoretic mobility, (Ue), of the stevensite particles in water, was measured at pH 2.5–12 by microelectrophoresis.
