Sepiolite-Palygorskite from the Hekimhan Region (Turkey)
Clays and Clay Minerals, 1995AbstractUpper Cretaceous-Tertiary marine clayey-calcareous rocks of the Hekimhan basin contain fibrous clay minerals in significant amounts. Ophiolitic rocks in the provenance area have contributed the elements to form the clay minerals. XRD, SEM, major, trace and REE analyses were applied to samples taken from several stratigraphic sections ...

Abstract The effects of pH on the structures, compositions, morphologies, Zeta potential, and gel properties of montmorillonite, palygorskite and their composite clays were investigated in the study. With the increase in pH, the above properties of montmorillonite, palygorskite and their composite clays showed different changing trends.

Sepiolite and Palygorskite in Japan
1984Abstract Recent investigations on palygorskite and sepiolite from Japan are summarized in relation to their mode of occurrence and mineral genesis. Description of the Japanese palygorskites has been confined to only two specimens from the Kuzuu district, represented by “karst region” where a thick sequence of carbonate rocks crops out extensively ...

Adsorption of terpenic compounds onto organo-palygorskite
Environmental Science and Pollution Research, 2017Essential oils from aromatic plants are currently mentioned as suitable tools for excellent protection of stored grains from insect pest attacks. The present work aimed to study the processes of the synthesis insecticidal formulation with clay. The active terpenic compounds of essential oil of Eucalyptus globulus (Eg) were fixed in the palygorskite by ...

Abstract Palygorskite (PAL) is a promising natural clay mineral for the preparation of bionic super anti-wetting coatings, a new application field of PAL. Here, the effects of modification of PAL on superamphiphobicity and microstructure of the PAL@fluorinated polysiloxane (PAL@fluoroPOS) superamphiphobic coatings were systematically studied.

Production of adsorbents from palygorskite clays
Chemistry and Technology of Fuels and Oils, 1987A manufacturing technology was developed for the production of adsorbents based on USSR palygorskite clays and intended for treating aromatic hydrocarbons to remove unsaturates. Upgraded adsorbents were obtained by decantation with subsequent dispersion in a laboratory mixer. Washing was monitored by flame photometry according to the contents of sodium,

Abstract This study was performed on palygorskite samples coming from the region of Timahdit which is in the Middle-Atlas, in the south-west of Morocco. The analysis and the comparison of the data of X-ray diffraction, chemical analysis, DTA, TGA, FTIR and SEM showed that this palygorskite crystallizes in a monoclinic system with three types of water

Chapter 7 Palygorskite and Sepiolite Applications
2006Publisher Summary This chapter discusses the palygorskite and sepiolite applications. The application of palygorskite and sepiolite are as varied as those described for kaolins and bentonites. The elongate shape of these two minerals results in unique colloidal properties, especially the resistance to high concentrations of electrolytes.
