Organo-montmorillonites as adsorbent materials for thiophanate-methyl removal: adsorption-desorption studies and technological applications
(Elsevier, 2020-08-06)
Thiophanate-methyl (TM) is a fungicide widely used in post-harvest treatment of pears and apples. The wastewater of this treatment usually is discharged to the natural rivers without treatment, with the consequent concern ...
Selective sorption of mercury(II) from aqueous solution with an organically modified clay and its electroanalytical application
(Taylor & Francis Inc, 2006-01-01)
The organo-clay used in this work was prepared from a Na-montmorillonite (Wyoming-USA deposit) by treatment with water solution of hexadecyltrimethylammonium cations. As organo-clays exhibit strong sorptive capabilities ...
Interrelations of structure, electric surface charge, and hydrophobicity of organo-mica and –montmorillonite, tailored with quaternary or primary amine cations. Preliminary study of pyrimethanil adsorption
(Elsevier Science SA, 2019-02)
In this work, organo-montmorillonite (organo-Mt) and organo-synthetic mica (organo-mica), obtained by quaternary or primary amine cations (octadecyltrimethylammonium (ODTMA) or octadecyl-amine (ODA), respectively) exchanged ...
Organo-montmorillonite with biogenic compounds to be applied in antifungal coatings
(Elsevier Science, 2020-01)
Antimicrobial surfaces are required to obtain more hygienic indoor environments. There are biogenic compounds like terpenoids, from plant essential oils, with potential antimicrobial activity. Besides, modified montmorillonites ...
Use of organo-montmorillonite for the nitrate retention in water: Influence of alkyl length of loaded surfactants
(Springer Nature, 2019-10-03)
The removal of NO3− from water was performed and compared among four organo-montmorillonites (OMt) with quaternary amine surfactants of different chain lengths [octadecyl trimethyl-(ODTMA), hexadecyl trimethyl-(HDTMA), ...
Removal of humic acid by organo-montmorillonites: Influence of surfactant loading and chain length of alkylammonium cations
(Springer, 2014-05)
In this study, the characterization and adsorption properties of montmorillonite (MMT) and organomontmorillonites with different surfactant/cationic exchange capacity (CEC) ratios (1 and 2) of tetradecyl trimethylammonium ...

(Taylor & Francis Inc, 2006-01-01)
The organo-clay used in this work was prepared from a Na-montmorillonite (Wyoming-USA deposit) by treatment with water solution of hexadecyltrimethylammonium cations. As organo-clays exhibit strong sorptive capabilities ...
Effect of modified montmorillonite on biodegradable PHB nanocomposites
(Elsevier Science, 2010-02)
Polymer nanocomposites, based on a bacterial biodegradable thermoplastic polyester, poly(hydroxybutyrate) (PHB), and two commercial montmorillonites (MT), Na-M (MT) and 30B-M (organically modified MT), were prepared by ...
