It is suggested that piperidine may be useful in the identification of clay minerals during differential thermal analysis, particularly in the differentiation of expanding and non-expanding lattice minerals. Differential thermal analysis of two montmorillonites showing similar X-ray powder photographs indicated large differences in the distribution of cationexchange sites. INTRODUCTION Allaway ...

MODIFICATION OF CLAYS WITH IONIC LIQUIDS FOR POLYMER NANOCOMPOSITES by Neung Hyun Kim In attempts to prepare nanofillers with enhanced compatibility with a polymer matrix, cationic and anionic clays susceptible to exchange of their interlamellar ions with a variety of other cations or anions, were selected. In order to treat cationic clay, montmorillonite, which contains sodium ions as interlay...

Acid activation is a chemical modification of minerals and mainly smectites, in order to enhance their surface properties reinforce adsorption capacity for specific ions. Acid-activated clays and, more specifically, inorganic acid-activated calcium montmorillonites are used the bleaching process vegetable oils, which holding third place world food consumption after cereals rice, remove chloroph...

This work aims first to characterize the Maastrichtian and Paleogene clays of Ouled Bou Sbaa phosphate deposit located in northern part Meskala Basin; as a second goal, most efficient clay fractions are tested identified for organic dyes removal. Several techniques methods have been adopted characterization clays: X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), fluoresc...

The appealing properties of surfactant-intercalated Montmorillonites (Organo-montmorillonite, OMt) were successfully investigated to propose an effective drug delivery system for metronidazole (MNE) antibiotic therapy. This represents a serious pharmaceutical concern due the adverse reactions and low targeting ability MNE. non-ionic surfactant Tween 20 was used functionalize montmorillonite, th...
