Hydrolysis of Penicillin G by Penicillin G Acylase Immobilized on Chitosan Microbeads in Different Reactor Systems
(Wiley-VCH Verlag Gmbh, Weinheim, 2011)
The kinetic parameters for penicillin G hydrolysis in systems with penicillin G acylase from Escherichia coli (free and immobilized on activated chitosan microbeads produced by electrostatic extrusion) were determined. The ...
Compost of Aquatic Weed Myriophyllum spicatum as Low-Cost Biosorbent for Selected Heavy Metal Ions
(Springer International Publishing Ag, Cham, 2014)
Aquatic weed Myriophyllum spicatum L. is one of the most invasive water plants known. In many countries, it is usually harvested and landfilled, where aerobic and anaerobic decomposition takes place. In this research, the ...
Biodiesel production by methanolysis of waste lard from piglet roasting over quicklime
(Elsevier Sci Ltd, Oxford, 2016)
Waste lard from piglet roasting and quicklime (basically CaO) as a priceless fatty feedstock and a cheap solid catalyst, respectively were tested for the biodiesel production by methanolysis in a batch stirred reactor at ...
The mechanism and kinetics of the tungsten (VI)-oxide reduction in the vertical tube reactor
(Editura Stiintifica Fmr, Bucharest, 2012)
Presented study shows the analysis of the process of reduction of WO3 powder with hydrogen in the vertical tube reactor, representing a new approach in comparison to the conventional methods in the horizontal tube reactor. ...
Study of the iron(III)-modified clinoptilolite in the adsorption of phosphate from aqueous medium: mechanism and kinetics
(Desalination Publ, Hopkinton, 2017)
Clinoptilolite-rich tuff (Z) enriched with Fe(III) was studied in the removal of phosphate ions present in aqueous medium at pH = 6.5. Fe(III) modification was performed by a simple wet impregnation giving the product (FeZ) ...
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 ...
Binary adsorption of nickel and zinc from aqueous solutions onto the Serbian natural clinoptilolite
(Taylor & Francis Inc, Philadelphia, 2016)
Sorption of the Zn2+ and Ni2+ ions by the Na+-enriched natural clinoptilolite (Na-CLI) from aqueous solutions containing both Zn2+ and Ni2+ ions at a range of concentrations has been studied at 298, 308, and 318K. It was ...
Kinetics, thermodynamics, and structural investigations on the removal of Pb2+, Cd2+, and Zn2+ from multicomponent solutions onto natural and Fe(III)-modified zeolites
(Springer, New York, 2015)
The adsorption of Pb2+, Cd2+, and Zn2+ from equimolar multicomponent solutions onto natural and Fe(III)-modified zeolites was studied by batch experiments in order to determine the influence of the competitive effect on ...
Effective removal of Reactive Orange 16 dye from aqueous solution by amine-functionalized sepiolites
(Desalination Publ, Hopkinton, 2019)
Natural and acid-activated sepiolites, functionalized by covalent grafting of [ 3-(2-aminoethylamino)propyl]trimethoxy-silane were used as adsorbents for the removal of an anionic Reactive Orange 16 dye from aqueous ...
Synthesis of Aliphatic Esters of Cinnamic Acid as Potential Lipophilic Antioxidants Catalyzed by Lipase B from Candida antarctica
(Springer, New York, 2013)
Immobilized lipase from Candida antarctica (Novozyme 435) was tested for the synthesis of various phenolic acid esters (ethyl and n-butyl cinnamate, ethyl p-coumarate and n-butyl p-methoxycinnamate). The second-order kinetic ...
