Synthesis, characterization and antimicrobial activity of pentagonal-bipyramidal isothiocyanato Co(II) and Ni(II) complexes with 2,6-diacetylpyridine bis(trimethylammoniumacetohydrazone)
(Taylor & Francis Ltd, Abingdon, 2016)
Pentagonal-bipyramidal isothiocyanato Co(II) and Ni(II) complexes with condensation product of 2,6-diacetylpyridine and trimethylammoniumacetohydrazide (Girard's T reagent) were synthesized and characterized by elemental ...
Polyvinyl alcohol PVA with poly ethylene Glycol PEG added as a binder for the powder compaction
(Belgrade : Serbian Ceramic Society, 2018)
During the compaction of the powder mixture of ZnO and Mn2O3 (MnCO3) and Fe2O3 compacts were find fragile for further handling. Poly vinyl alcohol PVA was used as a binder in an unusual 20% PVA content. We made as well 2% ...
Kvalitet flaširanih voda kao indikator njihove zdravstvene ispravnosti / Bottled water quality and redox potential as an indicator of their health safety
(Udruženje za tehnologiju vode i sanitarno inženjerstvo / Association for water technology and sanitary engineering, 2012)
Flaširanu vodu koja se koristi u konzumacione svrhe, a nalazi se na tržištu, zakonska regulativa obično svrstava u tri grupe: prirodnu mineralnu, prirodnu izvorsku i stonu vodu. Flaširane vode su prema sadržaju mineralnih ...
Uticaj pH vrednosti na izdvajanje H2S pri pripremi vode za piće
(Udruženje za tehnologiju vode i sanitarno inženjerstvo /Association for water technology and sanitary engineering, 2012)
Podzemne vode u svom sastavu pored organskih materija često sadrže i vodonik- sulfid. Uzimajući u obzir da se za uklanjanje organskih materija u procesima pripreme vode za piće često koriste anjonske smole u ovom radu je ...
