Influence of Chemically Modified Short Hemp Fiber Structure on Biosorption Process of Zn2+ Ions from Waste Water
(Korean Fiber Soc, Seoul, 2014)
Short hemp fibers, acquired as a waste from textile industry, were used as an efficient biosorbent for removal of zinc ions from polluted water. In order to obtain the material with better sorption properties, short hemp ...
Removal of Cu(II) from aqueous solutions by using fluidized zeolite A beads: Hydrodynamic and sorption studies
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
This study investigated potentials of fluidized bed systems with zeolite A beads for removal of heavy metal ions from aqueous solutions. Two commercial zeolite bead fractions (0.7 and 2.2 mm in diameter) were used, while ...
Solvent and structural effects in tautomeric 3-cyano-4-(substituted phenyl)-6-phenyl-2(1H)-pyridones: experimental and quantum chemical study
(Springer/Plenum Publishers, New York, 2014)
The tautomeric equilibria between 2-pyridone and 2-hydroxypyridine forms of methoxy, chloro, and nitro derivatives of 3-cyano-4-(2-, 3-, and 4-substituted phenyl)-6-phenyl-2(1H)-pyridones were evaluated from UV/Vis spectral ...
Removal of a Cationic Dye from Aqueous Solution by Microwave Activated Clinoptilolite-Response Surface Methodology Approach
(Springer International Publishing Ag, Cham, 2014)
Natural clinoptilolite from Zlatokop deposit, Serbia, was activated by microwave irradiations (10 min, 550 W) and its adsorptive efficiency for removal of crystal violet (CV) dye from aqueous solution was investigated. The ...
Development of New Cordierite-Based Refractory Coatings for Casting Applications
(Wiley, Hoboken, 2014)
In this study, new refractory coatings based on synthesized cordierite for the casting applications were developed. The investigation included starting raw materials characterization, synthesis of the cordierite, design ...
Effects of dielectric barrier discharge in air on morphological and electrical properties of graphene nanoplatelets and multi-walled carbon nanotubes
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
Multi-walled carbon nanotubes (MWCNTs) and graphene nanoplatelets (GNPs) have been functionalized by dielectric barrier discharge (DBD) in air. The extent of functionalization of MWCNTs and GNPs reaches a maximum at the ...
Densities, Viscosities, and Refractive Indices of the Ternary Mixture Dimethyladipate+2-Butanone+1-Butanol at T = (288.15 to 323.15) K
(Amer Chemical Soc, Washington, 2014)
Excess molar volumes V-E, refractive index deviations Delta n(D), and viscosity deviations Delta eta of the ternary dimethyladipate + 2-butanone + 1-butanol and binary 2-butanone + 1-butanol systems are determined from the ...
Volumetric and Viscometric Study of Binary Systems of Ethyl Butyrate with Alcohols
(Amer Chemical Soc, Washington, 2014)
The density, viscosity, and refractive index of binary mixtures consisting of ethyl-butyrate + 1-propanol, 2-methyl-1-propanol, 1-butanol, 3-methyl-1-butanol, or 1-hexanol have been measured at atmospheric pressure and ...
Synthesis and characterization of resorcinol formaldehyde carbon cryogel as efficient sorbent for imidacloprid removal
(Desalination Publ, Hopkinton, 2014)
Carbon cryogel (CC) has been prepared through sol gel polycondensation of resorcinol with formaldehyde in basic aqueous solution followed by freeze-drying and carbonization. Porous properties of CC analyzed by gravimetric ...
Discrimination between adsorption isotherm models based on nonlinear frequency response results
(Springer, Dordrecht, 2014)
A number of criteria are established for distinguishing between different adsorption isotherm types. These criteria are defined based on the adsorption isotherm derivatives up to the third order, which, on the other hand, ...
