Selective and sensitive determination of repaglinide in pharmaceuticals by voltammetric and LC methods
(Editions de l'Academie Republique Populaire, 2015)
Detailed electrochemical study and novel voltammetric and LC methods are presented for the determination of repaglinide (RPG) in pharmaceuticals. Repaglinide in methanol: buffer solution (20:80; v/v) shows one or two anodic ...
Inhibition effect of berberine on the corrosion of copper in acidic medium
(Editions de l'Academie Republique Populaire, 2013)
Inhibition of copper corrosion by berberine in 0.5 M HCl was investigated by electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization techniques. The inhibition efficiency of berberine was studied for ...
Mixed-ligand complexes of boric acid with organic biomolecules
(2012)
Boric acid forms meta-stable complexes with biomolecules like amino and hydroxy acids and stable complexes with the diol group containing carbohydrates, vitamins, and nucleotides, yielding mono-chelate (1: 1 complex) or ...
A simple flow injection spectrophotometric procedure for direct determination of copper(II) in environmental samples
(Chemical Publishing Co., 2014)
A new simple, rapid and sensitive flow-injection spectrophotometric detection method has been developed for the on-line determination of copper(II) in environmental water samples. The method is based on the measurement of ...
Analytical application of polymethylene blue-multiwalled carbon nanotubes modified glassy carbon electrode on anticancer drug irinotecan and determination of its ionization constant value
(Elsevier B.V., 2013)
The voltammetric behavior of anticancer drug irinotecan (IRT) was investigated at poly (methylene blue)/multi-walled carbon nanotube (PMB/MWCNT) modified glassy carbon electrode (GCE). The modified electrode surface was ...
Determination of pKa values of some antihypertensive drugs by liquid chromatography and simultaneous assay of lercanidipine and enalapril in their binary mixtures
(Elsevier B.V., 2010)
In this study, pKa values were determined using the dependence of the retention factor on the pH of the mobile phase for three ionizable substances, namely, enalapril, lercanidipine and ramipril (IS). The effect of the ...
Electrochemical preparation of sodium dodecylsulfate doped over-oxidized polypyrrole/multi-walled carbon nanotube composite on glassy carbon electrode and its application on sensitive and selective determination of anticancer drug: Pemetrexed
(Elsevier B.V., 2014)
Electrochemical oxidation of pemetrexed (PMX) was studied on bare, carboxylic acid functionalized multi-walled carbon nanotubes and over-oxidized polypyrrole modified (oo-PPy/MWCNTs-COOH/GCE) glassy carbon electrodes by ...
Electroanalytical characteristics of antipsychotic drug ziprasidone and its determination in pharmaceuticals and serum samples on solid electrodes
(Elsevier B.V., 2010)
Ziprasidone is a psychotropic agent used for the treatment of schizophrenia. Its oxidation was investigated electrochemically at boron-doped diamond and glassy carbon electrodes using cyclic, differential pulse, and square ...
Preparation and characterization of polyvinyl alcohol based copolymers as wound dressing fibers
(Taylor and Francis Inc., 2015)
Biocompatible polyvinyl alcohol/polyethylene glycol and polyvinyl alcohol/polypropylene glycol copolymer mats were prepared by electrospinning. The composite fiber mats were subjected to detailed physical analysis complemented ...
Determination of dissociation constants of some antifungal drugs by two different methods at 298 K
(2013)
The dissociation constants of eight antifungal drugs (fenticonazole, isoconazole, itraconazole, ketoconazole, miconazole, ornidazole, tinidazole, tioconazole) have been determined in water and acetonitrile-water binary ...
