T-2 toxin adsorption by hectorite [PDF]

Journal of the Serbian Chemical Society, 2009
The adsorption of T-2 toxin by the natural smectite mineral – hectorite at pH 3.0, 7.0 and 9.0 was investigated. The results of T-2 toxin adsorption on hectorite showed that the T-2 adsorption capacity decreased with increasing concentration of adsorbent

Effects of Added Silica Nanoparticles on Hectorite Gels [PDF]

The Journal of Physical Chemistry B, 2012
We present a study on the macroscopic, microscopic, and rheological behavior of mixtures of natural hectorite clay and different types of anionic Ludox silica spheres. Adding silica spheres to the weak hectorite gels leads the collapse of the suspensions, while the strong gels remain space-filling, though their storage modulus and the yield stress ...

The transformation of synthetic hectorite in the presence of Cu(II) [PDF]

Clays and Clay Minerals, 2009
AbstractThe influence of Cu(II) on the hydrothermal and thermal transformations of a synthetic hectorite was investigated by a combined approach using mainly X-ray diffraction, thermal analyses, and electron paramagnetic resonance spectroscopy. The presence of Cu(II) during hydrothermal treatment increased the crystallite size.

Tunable colorless and transparent copoly(ester imide)s and nanocomposites derived from an optimized composition [PDF]

Scientific Reports
A series of colorless and transparent copoly(ester imide)s (Co-CPEIs) were synthesized by reacting diamine p-xylylenediamine (p-XDA) with two types of dianhydrides of various molar contents, namely 2,7-dihydroxynaphthalene bis(trimellitate anhydride ...

Sites of Lu(III) Sorbed to and Coprecipitated with Hectorite

Environmental Science & Technology, 2009
The Lu(III) binding mechanisms by trioctahedral smectite hectorite in aqueous systems were investigated by extended X-ray absorption fine structure (EXAFS) spectroscopy. Coprecipitated hectorite (Lu755Hec), its precursor phase (Lu/Brucite), and the surface sorbed hectorite (Lu/SHCa1) were prepared as oriented samples to collect polarized EXAFS (P-EXAFS)

Improvement of Overall Skin Condition in Acne and Oily Prone Skin With an Amino Acid Cleanser Containing Salicylic Acid, Glucuronolactone, and Ceramides. [PDF]

J Cosmet Dermatol
ABSTRACT Background Cleansers and moisturizers are two of the most essential skincare categories, both of which have significant dermatological implications. However, most studies focus on the cleansing power of surfactants and their potential damage to the skin barrier.

Waterborne Cross-Linkable Polyacrylate Latex Coatings with Good Water Resistance and Strength Stabilized by Modified Hectorite. [PDF]

Polymers (Basel), 2021
Polyacrylate emulsions were prepared by Pickering emulsion polymerization with multi-modified hectorite as a modifier. The proper wettability of modified hectorite and the stability of O/W emulsions prove that modified hectorite has good emulsification ...
