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 ...
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) ...
A new kinetic model for the common juniper essenstial oil extraction by microwave hydrodistillation
(Chemical Industry Press, Beijing, 2019)
The main objective of the present study was to model the kinetics of essential oil extraction from swelled ground juniper berries by classic hydrodistillation (HD) and microwave-assisted hydrodistillation (MAHD). A new ...
Kinetics of sunflower oil methanolysis catalyzed by calcium oxide
(Elsevier, 2009)
The methanolysis of sunflower oil was studied in the presence of CaO previously calcined at various temperatures and the optimal temperature for CaO calcination was determined. The sigmoidal process kinetics was explained ...
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 ...
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 ...
A study of the removal of copper ions from aqueous solution using clinoptilolite from Serbia
(Springer, New York, 2011)
Toxic metal contamination of waste waters can be mitigated by metal adsorption to clay and zeolitic minerals, but in developing countries such environmental remediation can be cost prohibitive if these minerals are not ...
Removal of aqueous manganese using the natural zeolitic tuff from the Vranjska Banja deposit in Serbia
(Elsevier, Amsterdam, 2009)
The natural zeolite tuff from the Vranjska Banja deposit (Serbia) has been studied as sorbent for Mn(II) ions from aqueous solutions. The zeolite sample containing mainly clinoptilolite (more than 70%) removes Mn(II) ions ...
Influence of common juniper berries pretreatment on the essential oil yield, chemical composition and extraction kinetics of classical and microwave assisted hydrodistillation
(Elsevier Science Bv, Amsterdam, 2018)
The present paper dealt with the influence of the common juniper berries pretreatment on the yield, chemical composition and extraction kinetics of juniper essential oil (JEO) obtained by classical (HD) and microwave ...
Transesterification of used cooking sunflower oil catalyzed by hazelnut shell ash
(Renewable Energy, 2022)
Hazelnut shell ash was investigated as a new base catalyst for the transesterification of used cooking sunflower oil to biodiesel. To understand its catalytic properties, the prepared ash was characterized by EDX, XRD, ...
