Activation of glassy carbon electrodes by photocatalytic pretreatment
Dumanli, Onur; Onar, A. Nur (Pergamon-Elsevier Science Ltd, 2009)This paper describes a simple and rapid photocatalytic pretreatment procedure that removes contaminants from glassy carbon (CC) surfaces. The effectiveness of TiO2 mediated photocatalytic pretreatment procedure was compared ... -
Determination of Nitrates, Nitrites and Oxalates in Kale and Sultana Pea By Capillary Electrophoresis
Erdogan, Behice Yavuz; Onar, A. Nur (Bureau Food Drug Analysis, 2012)The objective of this research was to determine the concentrations of nitrate, nitrite and oxalate in two vegetables which are popular at Black Sea coast, namely kale (B. oleracea var. acephala) and sultana pea (Pisum ... -
Determination of Nitrates, Nitrites and Oxalates in Kale and Sultana Pea by Capillary Electrophoresis [2]
Erdogan, Behice Yavuz; Onar, A. Nur (Medwell Online, 2011)The objectives of this research were to determine the quantities of nitrate, nitrite and oxalate in two vegetables those are popular at Black Sea coast namely kale and sultana pea. The results were compared with the contents ... -
Determination of ticlopidine in pharmaceutical products
Tuerkoez, Ebru; Onar, A. Nur (Taylor & Francis Inc, 2007)The voltammetric behaviour of ticlopidine-HCl was studied using square-wave, sampled direct current and cyclic voltammetry. The drug showed a cathodic peak at -0.01V versus Ag/AgCl with hanging mercury drop electrode. The ... -
Effect of complexation on photocatalytic degradation of dissolved organic nitrogen compounds
Onar, A. Nur; Akdemir, Nesuhi (Taylor & Francis Inc, 2007)The effect of metal ions on TiO2 mediated photocatalytic oxidation for the determination of dissolved organic nitrogen compounds is investigated. Ethylenediaminetetraaceticacid was chosen as a model molecule for DON ... -
Electrochemical Characterization and Voltammetric Determination of beta-N-oxalyl-L-alpha,beta-diaminopropionic Acid in Grass Pea Seeds
Cetinkaya, Gulcan; Erdogan, Behice Yavuz; Onar, A. Nur (Taylor & Francis Inc, 2018)The oxidation of the neurotoxic amino acid, beta-N-oxalyl-L-alpha,beta-diaminopropionic acid was characterized by cyclic and square-wave voltammetries on a glassy carbon electrode. An electrochemical protocol was developed ... -
Homoarginine, beta-ODAP, and asparagine contents of grass pea landraces cultivated in Turkey
Onar, A. Nur; Erdogan, Behice Yavuz; Ayan, Ilknur; Acar, Zeki (Elsevier Sci Ltd, 2014)The seeds of grass pea (Lathyrus sativus L.), a drought tolerant crop, were analysed for quantitative determination of the free amino acids p-N-oxalyl-t-e,3-diaminopropionic acid (beta-ODAP), homoarginine and asparagine ...
