Accumulation of trace metals in marine organisms of the southeastern Adriatic coast, Montenegro
(Serbian Chemical Society, 2012)
The concentration and accumulation of trace metals (Co, Ni, As, Cd, Pb and Hg) were measured in seawater, sediments and marine organisms on the coastline of Montenegro. The obtained results of trace metals in sea grass and ...
Investigation of different extraction procedures for the determination of major and trace elements in coal by ICP-AES and ion chromatography
(Srpsko hemijsko društvo, Beograd, 2016)
This paper presents the extraction of major and trace elements from a coal sample, in deionized water, by using three different extraction techniques. Rotary mixing and ultrasonic extraction were examined for different ...
A pseudo-fluid representation of vertical liquid-coarse solids flow / Vertikalno kretanje tečnosti i čvrstih čestica tretirano kao pseudo-fluid
(Serbian Chemical Society, 2005)
The pseudo–fluid concept has been applied for the prediction of the pressure gradient and voidage in vertical liquid-coarse solids flow. Treating the flowing mixture as a single homogenous fluid, the correlation for the ...
The examination of parameters for lactic acid fermentation and nutritive value of fermented juice of beetroot, carrot and brewer’s yeast autolysate / Određivanje parametara mlečno-kisele fermentacije i nutritivne vrednosti fermentisanog soka cvekle, mrkve i autolizata pivskog kvasca
(Serbian Chemical Society, Belgrade, 2004)
The conditions for lactic acid fermentation based on a mixture of beetoot juice (Beta vulgaris L) and carrot juice (Daucus carota L) and different content of brewer’s yeast autolysate with Lactobacillus plantarum A112 and ...
New values of the polarity factor
(Serbian Chemical Society, 2000)
New values of the polarity factor χ for 96 substances are proposed. Estimation procedure is tested on the values of this factor from the original work of Halm and Stiel.44.
Health risk assessment of potentially harmful substances from fly ashes generated by coal and coal waste combustion / Procena rizika za potencijalno opasne supstance iz letećih pepela dobijenih sagorevanjem uglja i otpadnog uglja
(Serbian Chemical Society, 2023)
Lignite and coal waste used as feed fuels in thermal power plants
(TPPs) and semi-industrial fluidized bed boiler (FBB), as well as their representative fly ashes (FAs), were examined. Fly ashes were compared employing
anions ...
