A simple and rapid method for preparing carbon nanopore electrode ensemble by coating a glassy carbon electrode with chromate
(Hitit University, 2016)
A simple preparation method for carbon nanopore electrode ensemble (CNEE) was reported. The CNEE consists of a number of pinholes which remain after coating a carbon surface with chromate. The transformation from transient ...
Lead removal from industrial waste
(Hitit University, 2017)
In this study, the heavy metal removal performance of poly(2-hydroxyethyl methacrylate-N-methacryloyl-(L)-histidine methyl ester), poly(HEMA-MAH) cryogel, a known polymer, in HNO3 was investigated. To determine the heavy ...
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 ...
Characterization of boron doped Cobalt/Zinc acetate composite fibers
(Hacettepe University, 2009)
PVA/cobalt acetate/zinc acetate doped with boron composite fibers were prepared by electrospinning technique. Electrospinning was performed by putting solutions at different applied voltage in a range from 13 to 18 kV. The ...
Nanofibers by electrospinning of nylon 6 doped with boron
(Hacettepe University, 2009)
In this study, Nylon 6 was successfully cross-linked with boron using formic acid as solution. Electrospinning process was performed by putting hybrid nylon 6/boric acid solutions at different applied voltage in a range ...
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 ...
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 ...
