Geotechnical properties of some organoclays
Sadhana, 2013 The engineering characteristics of clay are dependant on its mineral and chemical structure. When the clay soils interacted with water, their volume and shear strength and compressibility properties change gradually. Large amount of decrease in terms of the shear strength of clay soils due to swelling is observed.

Triadimefon Interactions with Organoclays and Organohydrotalcites [PDF]
Soil Science Society of America Journal, 2000 We determined the ability of several organoclays (octadecylammonium‐ and hexadecyltrimethylammonium‐exchanged montmorillonite) and organohydrotalcites (dodecylsulfate‐ and dodecylbenzenesulfonate‐exchanged hydrotalcite) to sorb the uncharged pesticide triadimefon [1‐(4‐chlorophenoxy)‐3,3‐dimethyl‐1‐(1 H

Confinement of a Nonionic Surfactant Membrane Within a Montmorillonite as a New Way to Prepare Organoclay Materials [PDF]
Materials Research, 2016 The aim of this study was to prepare and characterize a hybrid layered material (organoclay) with a Na-montmorillonite and the triethylene glycol mono-n-decyl ether (C10E3) nonionic surfactant which forms a lamellar phase at room temperature.

Characterisation of organoclays and adsorption of p-nitrophenol : environmental application [PDF]
, 2011 Organoclays were synthesised through ion exchange of a single surfactant for sodium ions, and characterised by a range of method including X-ray diffraction (XRD), BET, X-ray photoelectron spectroscopy (XPS), thermogravimetric analysis (TGA), Fourier ...
