Development and validation of a simple thin-layer chromatographic method for the analysis of p-chlorophenol in treated wastewater / Validacija tankoslojne hromatografije kao metode za jednostavno određivanje p-hlorfenola u tretiranoj otpadnoj vodi
(Serbian Chemical Soc, Belgrade, 2012)
A thin-layer chromatographic (TLC) method with densitometric detection was established for the quantification of p-chlorophenol in wastewater. Degradation efficiency of p-chlorophenol was monitored after each treatment of ...
The effect of the particle shape and structure on the flowability of electrolytic copper powder I: Modeling of a representative powder particle / Uticaj oblika i strukture čestica na tečljivost elektrolitičkog bakarnog praha I - modelovanje reprezentativne čestice praha
(Serbian Chemical Society, 2003)
One of the most important properties of copper powder is its flow ability which depends on the shape and the structure of the powder particles. A procedure for the determination of a representative powder particle permitting ...
The effect of reversing current deposition on the apparent density of electrolytic copper powder / Uticaj reversne struje na nasipnu masu pri elektrolitičkom taloženju bakarnog praha
(Serbian Chemical Society, 2002)
The possibility of depositing copper powders with different apparent density by changing the shape of reversing current wave is shown. The morphology and crystallinity of powder particles can be varied considerably by ...
Factors affecting the microstructure of porous ceramics / Faktori koji utiču na mikrostrukturu porozne keramike
(Serbian Chemical Society, 2006)
In this study, porous ceramics were produced by using two methods: the polymeric sponge and foam method. A study of the effect of viscosity on the characteristics of the final product produced using the polymeric sponge ...
The effect of the particle shape and structure on the flowability of electrolytic copper powder, III: A model of the surface of a representative particle of flowing copper powder electrodeposited by reversing current / Uticaj oblika I strukture čestica na tečljivost elektrolitičkog bakarnog praha III - model površine reprezentativne čestice tečljivog bakarnog praha dobijenog elektohemijskim taloženjem reversnom strujom
(Serbian Chemical Society, 2004)
The structure of the surface of copper powder particles is discussed and correlated with the lowest apparent density at which copper powder can still flow. It is shown that such structures can be easily obtained in the ...
Electrodeposition of Fe powder from acid electrolytes / Elektrohemijsko taloženje Fe prahova iz kiselih elektrolita
(Serbian Chemical Society, 2008)
Polarization characteristics of the electrodeposition processes of Fe powders from sulfate and chloride electrolytes and the morphology of the obtained powders were investigated. The morphology depended on the anion pre ...
Flavonoids from flowers of Cephalaria pastricenis and their antiradical activity / Flavonoidi iz cvetova Cephalaria pastricensis i njihova antiradikalska aktivnost
(Serbian Chemical Society, 2004)
Two flavonoid glycosides 1 and 2 having the luteolin structure were isolated from flowers of the endemic plant species Cephalaria pastricensis. They were identified by 1H and 13C NMR, as well as UV/Vis spectroscopy. The ...
Removal of heavy metals from water using multistage functionalized multiwall carbon nanotubes
(Serbian Chemical Society, 2017)
The multistage synthesis of the multi-wall carbon nanotubes (MWCNT) modified with polyamidoamine dendrimers, A1/and A2/MWCNT, capable of cation removal, is presented in this work, as well as novel adsorbents based on these ...
The contents of heavy metals in Serbian old plum brandies / Sadržaj teških metala u starim srpskim rakijama šljivovicama
(Serbian Chemical Soc, Belgrade, 2013)
Seven elements, namely, arsenic, lead, cadmium, copper, zinc, iron and manganese were determined in 31 samples of Serbian plum brandies by application of atomic spectrometry techniques. Flame atomic absorption spectrometry ...
Speciation of selected trace and major elements in lignite used in 'Nikola Tesla A' power plant (Obrenovac, Serbia) / Specijacija odabranih mikro- i makroelemenata u uzorcima lignita termoelektrane 'Nikola Tesla A' (Obrenovac, Srbija)
(Serbian Chemical Society, 2005)
Four samples of milled lignite used in the "Nikola Tesla A" power plant located in Obrenovac near Belgrade, were subjected to a five-step sequential extraction, comprising of the following phases: distilled water, 1M ...
