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 ...
The possibility of application of zeolyte powders for the construction of membranes for carbon dioxide separation
(Savez hemijskih inženjera, Beograd, 2015)
The aim of this study was to construct a polymer-based mixed matrix membrane that could be used for waste gases treatment. Therefore, high permeability for the carbon dioxide and low permeability for other gases commonly ...
