Development of a flow-injection with spectrophotometric method for total iron in water samples
(Hacettepe University, 2017)
Asimple spectrophotometric flow-injection method is reported for the highly sensitive and fast determination of iron(III) and total iron. The method is based on the formation of iron(III)- (1-nitroso-2-naphthol-3,6 sulphonate) ...
Optimization of the schiff-base reaction of acetylacetone with biogenic amines
(Hitit University, 2017)
In this work, optimum conditions for the derivatization reaction of biogenic amines (histamine, tyramine, putrecine, tryptamine, phenylethylamine, cadaverine, spermidine and spermine) with acetylacetone have been determined. ...
Coal an impure fuel source: Radiation effects of coal-fired power plants in Turkey
(Hacettepe Üniversitesi, 2010)
Turkish coal is generally poor quality and the levels of chemical and radiological toxic trace elements in it are higher with respect to mean values of activity concentrations given in United Nations Scientific Committee ...
Synthesis, spectral, thermal studies of Co(II), Ni(II), Cu(II) and Zn(II)-arginato Complexes. crystal structure of monoaquabis(arginato‐κO,κN)copper(II). [Cu(arg)2(H2O)].NaNO3
(Chinese Chemical Society Taiwan, 2014)
Transition metal complexes of arginine (using Co(II), Ni(II), Cu(II) and Zn(II) cations separately) were synthesized and characterized by FTIR, TG/DTA-DrTG, UV-Vis spectroscopy and elemental analysis methods. Cu(II)-Arg ...
Simple, sensitive and reliable LC-DAD method of gemifloxacin determination in pharmaceutical dosage forms
(2012)
A sensitive, accurate, rapid, fully validated, reliable and easy method was developed for the quantification of gemifloxacin mesylate (GEM) using liquid chromatography (LC) with DAD detection. In this method; a reversed-phase ...

(2013)
In the present paper, rapid, sensitive, selective, accurate and precise analytical methodologies were developed for the determination of the antidepressant drug mirtazapine (MIR) using voltammetry and liquid chromatography. ...
Synthesis, characterisation and DFT calculations of azo-imine dyes
(Turkish Chemical Society, 2018)
In this study, azo dyes containing an imine group were synthesised by coupling p-hydroxybenzylidene aniline with the diazonium salts of p-toluidine, 4-aminophenol, aniline, p-chloroaniline, p-fluoroaniline and p-nitroaniline. ...
Nicotinamide-modified poly(HEMA-GMA)-Nic cryogels for removal of pesticides
(Turkish Chemical Society, 2018)
Chlordane is only one of the persistent pesticides used in some countries despite the ban. Removal of chlordane, a severe threat to all living things, was performed using nicotinamide-modified poly (2-hydroxyethyl ...
