(Rudarski radovi, Bor, 2010)
The presented results refer to the investigation of effect the mechanical-chemical activation of flotation tailings on copper, iron and sulfur leaching degree in the sulfuric-chloride solution with the addition of H2O2 as ...
Kvalitet reke Ibar od Biljanovca do Kraljeva / Quality of the river Ibar from Biljanovac to Kraljevo
(Srbija : Savez inženjera i tehničara Srbije, 2015)
Voda reke Ibar se koristi za vodosnabdevanje kao i za potrebe stanovništva mnogih mesta, stoga je praćenje kvaliteta vode reke Ibar od primarnog značaja za utvrđivanje kontaminiranosti vodenog ekosistema i zaštite čovekovog ...
Bioremediation of groundwater at the location 'Niteks' in Niš / Bioremedijacija podzemnih voda na lokaciji 'Niteks' u Nišu
(Udruženje za tehnologiju vode i sanitarno inžinjerstvo, Beograd, 2013)
This paper discusses the methods of bioremediation as an approach for remediation of groundwater contaminated by petroleum hydrocarbons. Successful application of these methods largely depends on the site conditions, which ...
Elektrohemijsko određivanje antimona na elektrodama sa poli(vinil alkohol)/glina kompozitom / Electrochemical detection of antimony on electrodes based on poly(vinyl alcohol)/clay composites
(Beograd : Savez inženjera i tehničara Srbije, 2019)
Sintetisani su kompoziti gline i poli(vinil alkohola) (PVA) sa masenim odnosima PVA/glina 10% i 20%. Kompoziti su naneti na površinu disk elektrode od staklastog ugljenika pomoću Nafiona. Tako modifikovane elektrode su ...
Determination of ionization constants (PKA) of β-hydroxy-β-arylalkanoic acids using high-pressure liquid chromatography
(University of Kragujevac, Faculty of Science, 2018)
pKa values of five β-hydroxy-β-arylalkanoic acids and ibuprofen were determined using the RP-HPLC method. Stationary phase was octadecyl modified (C-18) silica gel, and mobile phase was a mixture of methanol and one of ...
