Application of kinetic models to the sorption of disperse dyes onto alunite

Özacar, Mahmut; Şengil, İsmail Ayhan (ELSEVIER SCIENCE BV, 2004)

The sorption of three disperse dyes, namely, Disperse Blue 56 (DB56), Disperse Red 74 (DR74) and Disperse Yellow 119 (DY119), onto alunite has been studied in terms of pseudo-first- and second-order sorptions and intraparticle ...
Enhanced Adsorption of Hexavalent Chromium Ions on Polyamine Polyurea Polymer: Isotherm, Kinetic, Thermodynamic Studies and Batch Processing Design

Özer, Çiğdem; Boysan, Füsun; İmamoğlu, Mustafa; Yıldız, Salih Zeki (TAYLOR & FRANCIS INC, 2016)

In the present study, polyamine polyurea polymer was employed for adsorption of Cr(VI) ions from aqueous solution. Adsorption studies were carried out to examine the effects of parameters such as pH, contact time, initial ...
Evaluation of tannin biopolymer as a coagulant aid for coagulation of colloidal particles

Özacar, Mahmut; Şengil, İsmail Ayhan (ELSEVIER SCIENCE BV, 2003)

Tannin is a biodegradable anionic polymer. Tannin as a coagulant aid can be a potential substitute for synthetic anionic polyelectrolytes in water treatment because it can: (1)avoid the health effects from residual ...
Optimisation of Production Parameters Used in Turning Waste Cooking Oil as Fuel

Karabaş, Hülya (ASIAN JOURNAL OF CHEMISTRY, 2013)

In the present study, waste cooking oil with low free fatty acids content was used as feedstock for producing biodiesel. Biodiesel was produced by alkaline-catalyzed transesterification process, which was designed according ...
Optimization of Production Parameters of Tobacco Seed Oil Methyl Ester using Multi-Response Taguchi Method and MANOVA

Karabaş, Hülya; Boran, Semra; Yazğan, Harun Reşit (CHEM SOC PAKISTAN, 2019)

There is a growing recognition that using of biodiesel in large commercial systems based on sustainability, existing resources and residues can help to natural resources. Tobacco seed oil (TSO) is also used for biodiesel ...
Synthesis and characterization of hybrid iron oxide silicates for selective removal of arsenic oxyanions from contaminated water

Medhat Mohamed El-Moselhy; Ayten Ates; Çelebi, Ahmet (ACADEMIC PRESS INC ELSEVIER SCIENCE, 2017)

A series of hybrid silicates containing iron oxides was synthesized by adding various amounts of iron into silica on the basis of using post precipitation mechanism from aqueous solutions in order to form hydrated iron ...
Use of ion chromatography method on the determination of some anions in the water collected from Sakarya, Turkey

Altundağ, Hüseyin; Serife Agar; Altıntığ, Esra; Ateş, Asude; Sezen Sivrikaya (ACG PUBLICATIONS, 2019)

In this study simultaneous analysis of seven different anions (Fluoride, Chloride, Bromide, Nitrite, Nitrate, Phosphate, and Sulfate) in13 different water samples collected from Sakarya/Turkey and it was conducted with ion ...
Variables Affecting the Yield of Oil from Tobacco Seed

Parlak, Adnan; Karabaş, Hülya; Özsert, İbrahim (ASIAN JOURNAL OF CHEMISTRY, 2009)

In this study, a parametric study was implemented for the purpose of optimization of the efficient oil extraction for a continuous oil production plant, The Parameters affecting oil extraction from the tobacco seed oil in ...
