Lipophilicity assessment of some 5,5-disubstituted hydantoins by the means of reversed phase liquid chromatography / Procena lipofilnosti nekih 5,5-disupstituisanih hidantoina primenom tečne hromatografije na obrnutim fazama
(Association of the Chemical Engineers of Serbia, 2013)
The retention of some 5,5-disubstituted hydantoins was investigated by reversed phase high performance thin-layer chromatography (RP HPTLC) and reversed phase high-pressure liquid chromatography (RP HPLC). The mobile phases ...
Optimization of the synthesis of n-alkyl and n,n-dialkyl thioureas from waste water containing ammonium thiocyanate
(Savez hemijskih inženjera, Beograd, 2015)
The optimized methods for N-alkyl and N,N-dialkyl substituted thioureas synthesis starting from ammonium thiocyanates, waste water constituent from the production of tetramethylthiuram monosulfide (TMTS), and alkyl amine, ...
The effect of salinity on the sorption of cadmium ions from aqueous medium on Fe(III)-sepiolite / Uticaj saliniteta vode na sorpciju jona kadmijuma na Fe(III)-sepiolitu
(Association of the Chemical Engineers of Serbia, 2015)
In this study, the sorption of cadmium ions onto sepiolite modified with hydrated iron(III) oxide, Fe(III)-sepiolite, has been investigated in natural seawater, artificial seawater, aqueous solution of NaCl of the same ...
Comparison of cubic-plus-association and soave-redlich-kwong equations of state for prediction of vapor-liquid equilibrium of fischer-tropsch reaction mixture
(Savez hemijskih inženjera, Beograd, 2019)
Predictions of vapor liquid equilibrium for Fischer-Tropsch mixtures were com-pared using the classical Soave-Redlich-Kwong (SRK) and cubic-plus-asso-ciation (CPA) equations of state. The performance of the two equations ...
Selected trace element concentrations in ambient air and in horse chestnut leaves in Belgrade / Koncentracije odabranih elemenata u tragovima u vazduhu i u listovima divljeg kestena u Beogradu
(Association of the Chemical Engineers of Serbia, 2015)
In this study, airborne particulates (PM10) and leaves of horse chestnut were collected at selected urban sites in Belgrade, Serbia, in years 2006, 2009 and 2012. All samples were analysed for trace element concentrations ...
