Extraction of Essential Oil from Laurel Leaves by Using Microwaves

The effects of microwave power and time in solvent-free microwave extraction (SFME) on the yield and composition of the essential oil obtained from laurel (Laurus nobilis L.) leaves were studied. The extraction was also performed by hydrodistillation as a control. Specific gravities and refractive indices of the essential oils obtained by different methods and at various conditions were also examined. The main constituent of laurel essential oil was 1,8-cineole (630-730mg/mL). Essential oils obtained by SFME and hydrodistillation were comparable with respect to both yield and composition while the process time was reduced by 55-60% when SFME was used.


Recovery of Turkish Oil Shales by Electromagnetic Heating and Determination of the Dielectric Properties of Oil Shales by an Analytical Method
Hascakir, Berna; Akın, Serhat (American Chemical Society (ACS), 2010-01-01)
The effect of microwave irradiation on the recovery of three different oil shale samples was studied. To enhance the microwave efficiency, three different iron powders (Fe, Fe2O3, and FeCl3) and their three different doses (0.1, 0.5, and 1% by weight, each) were added to the samples as microwave receptors. The doses of each receptor were optimized for each oil shale sample based on the highest oil or gas production value obtained experimentally. During the experimental studies, the temperature distribution ...
Adsorption of volatile organic compounds on soil and prediction of desorption breakthroughs
Yeo, SD; Tuncer, E; Akgerman, A (Informa UK Limited, 1997-01-01)
Vapor extraction of volatile organic compounds from soil was investigated by performing adsorption and desorption experiments of trichloroethylene, trichloroethane, and chlorobenzene on soil particles. The adsorption breakthrough curves were obtained using a dynamic response technique based on frontal analysis chromatography. The shape of the breakthrough curves indicated that the adsorption process was close to an ideal adsorption system of no mass transfer resistance, no axial dispersion, and infinitesima...
Estimation of Binding Constants of Cd(II), Ni(II) and Zn(II) with Polyethyleneimine (PEI) by Polymer Enhanced Ultrafiltration (PEUF) Technique
Kadioglu, Sezin Islamoglu; Yılmaz, Levent; Ozbelge, H. Onder (Informa UK Limited, 2009-01-01)
Continuous and batch processes of polymer enhanced ultrafiltration for the estimation of binding constants of divalent cadmium, nickel, and zinc ions have been elaborated. Polyethyleneimine was used as a complexation agent. Effect of pH and ionic strength on the binding ability of target metal ions to polyethyleneimine were estimated by continuous mode PEUF system. A mathematical model was developed to estimate apparent complexation constants of metal ions with PEI. The development of this model, which is i...
Color formation in wheat starch based glucose syrups and use of commercially available and laboratory-prepared agricultural waste-based activated carbons for decolorization
Celebi, Ipek; Kincal, N. Suzan (Informa UK Limited, 2007-01-01)
Glucose syrups were produced from wheat starch using alpha-amylase at 97 degrees C for 45-90 min liquefaction times, followed by saccharification with amyloglucosidase at 60 degrees C for 18 h to study the color formation. This was followed by decolorization studies using 0.25 to 1.00 g activated carbon per g of syrup of the commercially available NORIT and several activated carbons prepared from apricot stones and hazelnut shells and husks on laboratory scale. Increase in liquefaction time resulted in high...
Removal of hexavalent chromium anions via polymer enhanced ultrafiltration using a fully ionized polyelectrolyte
HAKTANIR, CEREN; Ozbelge, H. Onder; Bicak, Niyazi; Yılmaz, Levent (Informa UK Limited, 2017-01-01)
A fully ionized polyelectrolyte was synthesized for Cr(VI) removal from aqueous solutions by continuous polymer enhanced ultrafiltration (PEUF). Effect of operating parameters such as pH, loading, polymer, and competing ion concentrations were examined. Highest Cr(VI) retention was obtained at a loading of 0.01 at pH 4. Increasing both polymer and chromate concentrations at a fixed loading of 0.01 decreased the retention which demonstrated the effect of crowding. In the presence of competing anions such as ...
