The adsorption of salicylic acid, acetylsalicylic acid and atenolol from aqueous solutions onto natural zeolites and clays: Clinoptilolite, bentonite and kaolin
(Elsevier, Amsterdam, 2013)
In this study, adsorption of salicylic acid, acetylsalicylic acid and atenolol from aqueous solutions onto clinoptilolite modified with sorbed metallic cations (Cu(II), Zn(II), Ni(II) or Mn(II)) have been probed. Natural ...
Fumonisin B-1 adsorption to octadecyldimethylbenzyl ammonium-modified clinoptilolite-rich zeolitic tuff
(Elsevier, Amsterdam, 2007)
Adsorption of fumonisin B-1 (FB1) on natural clinoptilolite-rich zeolitic tuff, modified with different amounts (2, 5 and 10 mmol M+/100 g) of octadecyldimethylbenzyl ammonium (ODMBA) ions, at pH 3, 7 and 9, was investigated. ...
Competitive adsorption of polycyclic aromatic hydrocarbons on organo-zeolites
(Elsevier, Amsterdam, 2007)
Sorption of polycyclic aromatic hydrocarbons on organo-zeolites was investigated to determine sorbent-sorbate interaction. The hydrophobic character of the surface of the organo-zeolites was studied using in water vapor ...
An investigation of diclofenac sodium release from cetylpyridinium chloride-modified natural zeolite as a pharmaceutical excipient
(Elsevier Science Bv, Amsterdam, 2013)
In this paper, investigations of zeolite - cationic surfactant - drug composites as drug carriers were performed. For that purpose, after adsorption of the model drug - diclofenac sodium (DS) onto composites obtained by ...
Ibuprofen and diclofenac sodium adsorption onto functionalized minerals: Equilibrium, kinetic and thermodynamic studies
(Elsevier, Amsterdam, 2022)
Cationic surfactant - octadecyldimethylbenzyl ammonium chloride (ODMBA) was used for modification of the three natural raw materials - bentonite, kaolin and zeolite. Adsorption of ODMBA by minerals occurred via ion exchange ...
Natural zeolites for pharmaceutical formulations: Preparation and evaluation of a clinoptilolite-based material
(Elsevier, Amsterdam, 2016)
Aim of this work was the preparation, starting from a clinoptilolite-rich rock, of a material suitable for the development of pharmaceuticals. In particular, the purpose was to obtain a reproducible product that maximizes ...
Use of surface modified natural zeolite (SMNZ) in pharmaceutical preparations. Part 2. A new approach for a fast functionalization of zeolite-rich carriers
(Elsevier, Amsterdam, 2016)
Main purpose of the research was to define an operative protocol, applicable at industrial scale, optimizing the functionalization of natural zeolites with surfactants, especially in pharmaceutical and environmental sphere. ...
Removal of emerging contaminants from water by zeolite-rich composites: A first approach aiming at diclofenac and ketoprofen
(Elsevier, Amsterdam, 2020)
In this study, composites of the natural zeolites and cationic surfactants cetylpyridinium chloride and Arquad (R) 2HT-75 were used for removal of two emerging contaminants - diclofenac sodium and ketopmfen. Modifying a ...
Surfactant modified zeolites - new efficient adsorbents for mycotoxins
(Elsevier, Amsterdam, 2003)
The in vitro mycotoxins adsorption by natural clinoptilolite-heulandite rich tuff modified with different amounts of octadecyldimethyl benzyl ammonium chloride (Do) and dioctadecyldimethyl ammonium chloride (Pr) was ...
