Adsorption of chromium (VI) from aqueous solutions onto amine-functionalized natural and acid-activated sepiolites
(Elsevier Science Bv, Amsterdam, 2013)
Chromium(VI) adsorption onto amine-functionalized sepiolites from aqueous solution at 298 K was investigated. Natural and add-activated sepiolites were functionalized by covalent grafting [3-(2-aminoethylamino)propyl] ...
Agricultural waste as a source of peroxidase for wastewater treatment: Insight in kinetics and process parameters optimization for anthraquinone dye removal
(Environmental Technology & Innovation, 2021)
The number of different technologies available for colored wastewater treatment shows the vastness of the issue. Finding the most feasible one, yet taking into account the cost, the efficiency and eco-friendliness is like ...
Removal of Co2+ ions from aqueous solutions using iron-functionalized sepiolite
(Elsevier Science Sa, Lausanne, 2012)
The efficiency of iron-functionalized sepiolite for the removal of Co2+ ions from aqueous solutions was determined under different experimental conditions, using the batch method. The ionization constants of the surface ...
Formic acid oxidation on Pt-Au nanoparticles: Relation between the catalyst activity and the poisoning rate
(Elsevier Science Bv, Amsterdam, 2012)
Pt-Au nanoparticles supported on high area carbon were prepared by simultaneous reduction of Au and Pt precursors and by reduction of Pt precursor on already prepared Au nanoparticles. The first method produced a solid ...
Thermodynamic and spectroscopic interpretation of molecular interactions of nicotine plus alcohol binary mixtures
(Academic Press Ltd- Elsevier Science Ltd, London, 2016)
Density rho, viscosity eta and refractive index n(D) have been experimentally measured for four binary mixtures nicotine + 1-butanol, nicotine + 2-butanol, nicotine + 1,2-propanediol and nicotine + 1,3-propanediol over the ...
Ethanol influenced fast microwave-assisted extraction for natural antioxidants obtaining from spent filter coffee
(Elsevier, Amsterdam, 2013)
Ethanol influenced microwave-assisted extraction was performed for obtaining of natural antioxidants from spent filter coffee. The process included response surface methodology which represented the significance of both ...
Nano- and Micro-Scale Surface Modification of FCC Metal Using High Submerged Cavitating Water Jet
(Springer, New York, 2013)
The aim of this paper is to establish a possible application of the cavitation phenomenon as an efficient method to modify surface properties at the nano and micro levels. Commercial-purity copper was subjected to high ...
Silicon-doped biphasic alpha-calcium-phosphate/hydroxyapatite scaffolds obtained by a replica foam method using uniform pre-annealed spherical particles
(Elsevier Science Bv, Amsterdam, 2012)
In this study, spherical particles of hydroxyapatite (HA) and alpha-tricalcium phosphate (alpha-Ca-3(PO4)(2): alpha-TCP) doped with different amounts of silicon were used for the preparation of scaffolds. The scaffolds ...
Toward Optimum Working Fluid Mixtures for Organic Rankine Cycles using Molecular Design and Sensitivity Analysis
(Amer Chemical Soc, Washington, 2013)
This work presents a Computer-Aided Molecular Design (CAMD) method for the synthesis and selection of binary working fluid mixtures used in Organic Rankine Cycles (ORC). The method consists of two stages, initially seeking ...
Experimental measurement and modelling of viscosity of the binary systems pyridine or nicotine with polyethylene glycols at T = (288.15-333.15) K. New UNIFAC-VISCO and ASOG-VISCO interaction parameters
(Elsevier Science Bv, Amsterdam, 2013)
Viscosities of four binary mixtures: pyridine + PEG200, pyridine + PEG400, nicotine + PEG200 and nicotine + PEG400 have been measured in temperature range 288.15-333.15 K with temperature step of 5 K and at the atmospheric ...
