Thermal study and mechanism of Ag2S oxidation in air
(Springer, Dordrecht, 2013)
The results of thermal study and mechanism of the oxidation process of synthetic Ag2S in air are presented in this article based on the comparative analysis of DTA and XRD results, as well as by constructed phase stability ...
Removal of heavy metals from aqueous solution using natural and fe(iii) oxyhydroxide clinoptilolite
(Springer, New York, 2013)
The increasing levels of industrial wastewater released to the environment present a serious threat to human health, living resources, and ecological systems. Fe-modified zeolites were developed and tested for removal of ...
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 ...
Influence of Soil Type and Physical-Chemical Properties on Uranium Sorption and Bioavailability
(Springer International Publishing Ag, Cham, 2012)
This work was undertaken to study the influence of soil type and its physical and chemical properties on uranium sorption and bioavailability, in order to reduce the uncertainty associated with this parameter in risk ...
Effects of additives on nickel (ii)-chloride hydrogen reduction for production of nanocomposite catalysts
(Editura Stiintifica Fmr, Bucharest, 2012)
Catalysts based on nickel, as active component, exhibit suitable properties in various heterogeneous catalysis processes; however, they quickly deactivate due to deposits formation during exploitation and sintering at ...
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 ...
Chemometric approach for prediction of uranium pathways in the soil
(Walter De Gruyter Gmbh, Berlin, 2014)
Understanding the effect of soil parameters (pH, Eh and organic and inorganic ligands availability) on uranium mobility under different geochemical conditions is fundamental for reliable prediction of its behaviour and ...
The assessment of maturation changes of humic coal organic matter - Insights from closed-system pyrolysis experiments
(Elsevier, Amsterdam, 2016)
The artificial maturation changes of the humic coal organic matter (OM) from late diagenesis to the semianthracite stage of coalification were investigated using the closed-system pyrolysis. Two extracted coal samples, a ...
