Keskin, Can Serkan; Özdemir, Abdil; Şengil, İsmail Ayhan (PARLAR SCIENTIFIC PUBLICATIONS (P S P), 2011)

Electrocoagulation (EC) is one of the widely used methods for the removal of dye pollutants from dye contaminated effluents. In this study, removal of binary dye mixtures from aqueous solution was carried out by direct ...
Detection of Cysteine with Glutathione-capped Silver Nanoparticles in the Presence of Ni2+ Ions

Özdemir, Abdil; Keskin, Can Serkan; Yılmazer Keskin, Semra (CHIMINFORM DATA S A, 2012)

Glutathione-capped silver nano particles (AgGSH) were prepared by the reduction of silver nitrate using NaBH4, and then were used for the detection of cysteine (Cys) in aqueous solution in the presence of Ni2+ ions via ...
Determination of Heavy Metal Contamination in Roadside Surface Soil by Sequential Extraction

Altundağ, Hüseyin; Keskin, Can Serkan (HARD, 2013)

This paper investigated concentrations of heavy metals in roadside surface soil samples collected from the D-100 highway in Sakarya, Turkey. The sequential extraction procedure has been applied to 24 soil surface samples ...
Determination of heavy metals in lower Sakarya river sediments using a BCR-sequential extraction procedure

Dündar, Mustafa Şahin; Altundağ, Hüseyin; Eyüpoğlu, Volkan; Keskin, Can Serkan (SPRINGER, 2012)

A BCR-sequential extraction procedure for the determination of extractable heavy metals was applied to sediments of various rivers and lakes. There are many rivers basins in Turkey. Sakarya River Basin is one of the most ...
Development of a new sensor material based on crystalline colloidal arrays embedded into polymer network

Keskin, Can Serkan; Özdemir, Abdil (MAIK NAUKA/INTERPERIODICA/SPRINGER, 2011)

This study reports the development of a novel sensing material that reports on analyte concentrations via diffraction of visible light from polymerized crystalline colloidal arrays (PCCA). The PCCA contains periodic ...
Quantification of Chlordiazepoxide and Pipenzolate Bromide in Tablets and Comparison with Chromatographic Results

Keskin, Can Serkan; Özdemir, Abdil (ASIAN JOURNAL OF CHEMISTRY, 2009)

Multiple methods were developed for the quantitative analysis of binary mixture of chlordiazepoxide and pipenzolate bromide in a pharmaceutical preparation. These techniques are categorized into chemometric, graphical and ...
Quantitative Determination of Glycine in Aqueous Solution Using Glutamate Dehydrogenase-Immobilized Glyoxal Agarose Beads

Yılmazer Keskin, Semra; Keskin, Can Serkan (HUMANA PRESS INC, 2014)

In this study, an enzymatic procedure for the determination of glycine (Gly) was developed by using a column containing immobilized glutamate dehydrogenase (GDH) on glyoxal agarose beads. Ammonia is produced from the ...
REMOVAL OF A BINARY DYE MIXTURE OF CONGO RED AND MALACHITE GREEN FROM AQUEOUS SOLUTIONS USING A BENTONITE ADSORBENT

Özdemir, Abdil; Keskin, Can Serkan (CLAY MINERALS SOC, 2009)

An important application of clay is as a solid adsorbent for industrial dyes. The aim of the present work was to carry out an experimental-theoretical study of the adsorption of dye mixtures, namely malachite green (MG) ...
