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 ...
Differences in coating mechanism of structurally different aluminosilicates observed through the thermal analysis
(Springer, Dordrecht, 2018)
Systematic modification of three structurally different minerals (zeolite, mica, and vermiculite) was carried out with the aim of determining the modification mechanism and exposing the hydrophobic surface that can be used ...
Isopiestic determination of the osmotic and activity coefficients of the {yKNO(3) + (1-y)K2HPO4}(aq) system at T=298.15 K
(Academic Press Ltd- Elsevier Science Ltd, London, 2012)
The osmotic coefficients of aqueous mixtures of KNO3 and K2HPO4 have been measured at T = (298.15 +/- 0.01) K by the isopiestic vapor pressure method at KNO3 ionic strength fractions y = (0.20581, 0.43631, 0.61099, and ...
Sugar Profile of Kernels as a Marker of Origin and Ripening Time of Peach (Prunus persicae L.)
(Springer, Dordrecht, 2015)
Large amounts of fruit seeds, especially peach, are discarded annually in juice or conserve producing industries which is a potential waste of valuable resource and serious disposal problem. Regarding the fact that peach ...
Mechanical activation of talc in high-energy speed rotary mechanoactivator
(Elsevier Sci Ltd, Oxford, 2012)
This paper presents the results of research on mechanical activation of raw talc in a high-energy speed rotary mechanoactivator. The results of research on effect of mechanically activated talc on the degree of recovery ...
Preparation and characterization of zinc-exchanged montmorillonite and its effectiveness as aflatoxin B-1 adsorbent
(Elsevier Science Sa, Lausanne, 2012)
A zinc-exchanged montmorillonite (Zn-MONT) was prepared from a natural montmorillonite (MONT) and the adsorption of aflatoxin B-1 (AFB(1)) was investigated at pH 3 and 7. Characterization of Zn-MONT was done by determination ...
Mechanism of stearic acid adsorption to calcite
(Elsevier, Amsterdam, 2013)
This paper presents the interpretation of binding mechanism of stearic acid for calcite surface in two modification methods. In the "dry" method, a surface dissociation of stearic acid is assumed where H+ ion goes to a ...
Can the origin of some metals in the seagrass Posidonia oceanica be determined by the indexes of metals pollutions?
(Springer Heidelberg, Heidelberg, 2015)
To assess metal pollution, Fe, Mn, Cu, Zn, Pb, Ni, Co, As, Cd, and Hg contents in samples of the seagrass Posidonia oceanica and surface sediment, collected at eight locations along the Montenegrin coast, were determined. ...
Adsorption of the mycotoxin zearalenone by clinoptilolite and phillipsite zeolites treated with cetylpyridinium surfactant
(Elsevier, Amsterdam, 2017)
In this study, organozeolites were prepared by treatment of the natural zeolites (clinoptilolite and phillipsite) with cetylpyridinium chloride (CP) equivalent to 50 and 100% of their external cation exchange capacities ...
Insecticidal Potential of Natural Zeolite and Diatomaceous Earth Formulations Against Rice Weevil (Coleoptera: Curculionidae) and Red Flour Beetle (Coleoptera: Tenebrionidae)
(Oxford Univ Press Inc, Cary, 2012)
Insecticidal potential of natural zeolites and diatomaceous earths originating from Serbia against Sitophilus oryzae (L.) and Tribolium castaneum (Herbst) was evaluated. Two natural zeolite formulations (NZ and NZ Modified) ...
