Adsorption of the herbicide 2,4-D on organo-palygorskite [PDF]
Applied Clay Science, 2010 Among the clay minerals, montmorillonite is the most extensively studied material using as adsorbents, but palygorskite and its organically modified products have been least explored for their potential use in contaminated water remediation. In this study, an Australian palygorskite was modified with cationic surfactants octadecyl trimethylammonium ...

Effects of the hydrophilic–lipophilic balance of inorganic nanoparticles on the properties of a non-aqueous drilling fluid with organo-palygorskite [PDF]
Clay MineralsAbstract The use of nanoparticles in the composition of drilling fluids can improve some of their properties (e.g. thermal, mechanical, electrical and rheological) due to their small size and high surface area, which can diminish the loss of fluid to the formation, thereby increasing thermal conductivity, reducing friction and improving well ...

Nafion/SiO2@TiO2‐palygorskite membranes with improved proton conductivity
Journal of Applied Polymer Science, Volume 139, Issue 21, June 5, 2022., 2022 The study introduces insights on the preparation and use of TiO2‐palygorskite and SiO2@TiO2‐palygorskite heterostructured nanoparticles as nanofiller of Nafion for increasing water stability and proton conductivity. Results prove that the composite membranes show improved proton conductivity at high temperature, broadening so the temperature range of ...

Sedimentology, Volume 72, Issue 6, Page 1860-1898, October 2025.ABSTRACT Detailed analysis of Lutetian–Bartonian deposits in the Paris Basin (‘Marnes et Caillasses’ Formation) provides new evidence of concomitant magnesian fibrous clays (palygorskite and sepiolite) and early microcrystalline dolomite. Although relatively uncommon in sedimentary archives, palygorskite and sepiolite are found in a wide range of ...
