Determination of nitrate by the IE-HPLC-UV method in the brain tissues of Wistar rats poisoned with paraquat / Određivanje nitrata IE-HPLC-UV metodom u moždanim tkivima Wistar pacova trovanih parakvatom
(Srpsko hemijsko društvo, Beograd, 2007)
This work was a part of an initial study regarding the involvement of reactive nitrogen species (RNS) in paraquat (PQ) neurotoxicity. The nitrate concentration in the vulnerable regions of the brain (cortex, striatum and ...
Rheological and droplet size analysis of W/O/W multiple emulsions containing low concentrations of polymeric emulsifiers / Određivanje reoloških karakteristika i veličine kapi W/O/W višestrukih emulzija dobijenih pri niskoj koncentraciji polimernih emulgatora
(Srpsko hemijsko društvo, Beograd, 2009)
Multiple emulsions are complex dispersion systems which have many potential applications in pharmaceutics, cosmetics and the food industry. In practice, however, significant problems may arise because of their thermodynamic ...
Acid-base equilibria of 2,4-diiodo-6-methylphenylcarbamoylmethyl iminodiacetic acid and its labeling with technetium-99m / Kiselinsko-bazne ravnoteže 2,4-dijod-6-metilfenilkarbamoilmetil iminodisirćetne kiseline i obeležavanje tehnecijumom-99m
(Srpsko hemijsko društvo, Beograd, 2006)
The acid-base equilibria of a novel hepatobiliary imaging agent, 2,4-diiodo-6-methylphenylcarbamoylmethyl iminodiacetic acid (DIIODIDA) were studied. The potentiometrically determined acidity constants of the second ...
Spectrophotometric investigations of the reaction between gold(III) and potassium iodide / Spektrofotometrijsko ispitivanje reakcije zlata(III) sa kalijum-jodidom
(Srpsko hemijsko društvo, Beograd, 2000)
The equilibria of the complex formation between AuCl4-n(OH)n- and I- was studied spectrophotometrically in aqueous solutions containing KI:Au(III)≤2 in the acidity range from 1 M HCl to pH 7 at 25 ºC. From the hydrogen ion ...

(Srpsko hemijsko društvo, Beograd, 2000)
1. Introduction 2. Basic characteristics of derivative spectrophotometry 2.1. Increase of spectra resolution 2.2. Elimination of the influence of baseline shift and matrix interferences 2.3. Enhancement of the detectability ...
Spectrophotometric determination of fluocortolone in tablets using 1,4-dihydrazinophthalazine / Spektrofotometrijsko određivanje fluokortolona u tabletama sa reagensom 1,4-dihidrazinoftalazinom
(Srpsko hemijsko društvo, Beograd, 2000)
The proposed method for the determination of fluocortolone is based on the formation of a stable, yellow coloured hydrazone product with 1,4-dihydrazinophthalazine as the reagent. Heating at 85 °C for 2 h was found to be ...
A study of novel cobalt(II) octaazamacrocyclic complexes with aminocarboxylates or their derivatives / Proučavanje novih kompleksa kobalta(II) sa oktaazamakrociklom i aminokarboksilatima ili njihovim derivatima
