Adsorption of o-, m- and p-nitrophenols onto organically modified bentonites
Koyuncu, Hulya; Yildiz, Nuray; Salgin, Ugur; Koroglu, Fatmanur; Calimli, Ayla (ELSEVIER SCIENCE BV, 2011)Experiments were conducted on the adsorption characteristics of o-, m- and p-nitrophenols by organically modified bentonites at different temperatures. Two organobentonites (HDTMA-B and PEG-B) were synthesized using ... -
Extraction of sesame seed oil using supercritical CO2 and mathematical modeling
Doker, Onur; Salgin, Ugur; Yildiz, Nuray; Aydogmus, Mihrican; Calimli, Ayla (ELSEVIER SCI LTD, 2010)In this work, extraction of sesame oil from sesame seeds using supercritical CO2 was carried out. The effect of operating parameters such as pressure, temperature, and supercritical CO2 flow rate and particle size on ... -
Heavy metal removal from aqueous solution by Pseudevernia furfuracea (L.) Zopf
Ates, Ayten; Yildiz, Atilla; Yildiz, Nuray; Calimli, Ayla (WILEY-V C H VERLAG GMBH, 2007)The present study was carried out in a batch system using a lichen (Pseudevernia furfuracea (L.) Zopf) for the sorption of nickel(II) and copper(II) ions from water. Particularly, the effect of pH, contact time and temperature ... -
A parametric study of phenolic compounds desorption performance from organobentonite by supercritical fluids
Salgin, Ugur; Yildiz, Nuray; Koeroglu, Fatmanur; Calimli, Ayla (ELSEVIER SCIENCE BV, 2007)Supercritical fluid desorption has been carried out in a fixed bed column to desorp nitrophenolic compounds from organically modified bentonite. The experiments were carried out in the sequence of synthesis of organobentonite ...
