Removal of nickel(II) ions from aqueous solutions using the natural clinoptilolite and preparation of nano-NiO on the exhausted clinoptilolite
(Elsevier Science Bv, Amsterdam, 2010)
The natural zeolite tuff (clinoptilolite) from a Serbian deposit has been studied as adsorbent for Ni(II) ions from aqueous solutions. Its sorption capacity at 298K varies from 1.9mg Nig(-1) (for the initial solution ...
Non-linear frequency response analysis of the kinetics of electrochemical reactions: a case study – ferrocyanide oxidation kinetics
(Serbian Chemical Society, Belgrade, 2010)
In general, electrochemical (EC) systems are non-linear, which means they respond nonlinearly to a frequency-dependent periodic input perturbation of high amplitude imposed around a steady-state. In addition, the kinetics ...
Extraction of sage (Salvia officinalis L.) by supercritical CO2: Kinetic data, chemical composition and selectivity of diterpenes
(Elsevier Science Bv, Amsterdam, 2010)
The supercritical carbon dioxide (SFE) extraction of Dalmatian sage (Salvia officinalis L) was investigated and compared to extraction performed by Soxhlet ethanol-water (70:30) mixture extraction (SE) and hydrodistillation ...
Hydrogel based on chitosan, itaconic acid and methacrylic acid as adsorbent of Cd2+ ions from aqueous solution
(Elsevier Science Sa, Lausanne, 2010)
A hydrogel has been synthesized by ionic crosslinking of chitosan (Ch) with itaconic acid (IA), followed by a free radical polymerization and crosslinking of Ch/IA network by adding methacrylic acid and the crosslinker. ...
On the thermal degradation of 3-methylaminopropylamine captured inside the aluminum phosphate analog of ULM-3
(Springer, Dordrecht, 2010)
An open-framework aluminophosphate analog of the fluorogallophosphate structure-type ULM-3 was obtained by hydrothermal crystallization of an aqueous aluminum phosphate suspension in the presence of 3-methylpropylamine ...
Modeling the kinetics of calcium hydroxide catalyzed methanolysis of sunflower oil
(Elsevier, 2010)
The kinetics of Ca(OH)2-catalyzed methanolysis of sunflower oil was studied at a moderate temperature (60 °C), a methanol-to-oil molar ratio (6:1) and different catalyst amounts (from 1% to 10% based on oil weight). The ...
