Modifikovanje mineralnog otpada mehano-hemijskim tretmanom / Modification of mineral waste by mechanical-chemical treatment
(Savez inženjera i tehničara Srbije, Beograd, 2009)
U radu su prikazani rezultati tretiranja Borske flotacijske jalovine (BFJ) u cilju definisanja optimalnog tehno-ekonomskog procesa recikliranja. Borska flotacijska jalovina ima u svom sastavu makroskopski posmatrano dve ...
Mogućnosti prerade nestandardnih koncentrata bakra i zaštita životne sredine / Possibilities for treatment of non-standard copper concentrates and environmental protection
(Naučno-stručno društvo za zaštitu životne sredine Srbije - Ecologica, Beograd, 2012)
Problemi koji se odnose na industrijsko zagađenje, iz godine u godinu postaju sve intezivniji i značajniji, kako na lokalnom, tako i na globalnom nivou. Osnovni razlog su emisije različitih zagađujućih materija koje nastaju ...
Determination of the phenolic profile of peach (Prunus persica L.) kernels using UHPLC-LTQ OrbiTrap MS/MS technique
(Springer, New York, 2018)
Recently, search for new natural sources of compounds with health-enhancing properties prompted interest in fruit kernels. This paper aims to assess peach kernels as a source of nutritionally important compounds, such as ...
Transformations of mechanochemical activated Na2CO3
(Univerzitet u Beogradu - Rudarsko-geološki fakultet, Beograd, 2022)
During mechanical activation, energy of treated material is increase to a higher level. This can lead to chemical transformation of the activated material. This is the point where we can talk about mechanochemical ...
Ispitivanje mogućnosti dobijanja montmorilonita modifikovanog jonima bakra kao adsorbenta aflatoksina B1
(Savez inženjera i tehničara Srbije, Beograd, 2009)
U ovom radu su dati rezultati ispitivanja mogućnosti dobijanja materijala za adsorpciju aflatoksina B1 modifikacijom minerala montmorilonita jonima bakra. Ispitivanja su rađena na bentonitskoj glini koja se eksploatiše u ...
Primena različite otpadne biomase u očuvanju i unapređenju životne sredine / Application of various waste biomass in the preservation of natural environment
(Naučno-stručno društvo za zaštitu životne sredine Srbije - Ecologica, Beograd, 2011)
Poslednjih godina vršena su obimna istraživanja sa ciljem da se nađu alternativni i ekonomski održivi adsorbenti za tretman otpadnih voda, kako u razvijenim, tako i u manje razvijenim zemljama. Biosorbenti koji su ekonomski ...
Structural features of two novel alluaudite-like arsenates Cd1.16Zn2.34(AsO4)(1.5)(HAsO4)(H2AsO4)(0.5) and Cd0.74Mg2.76(AsO4)(1.5)(HAsO4)(H2AsO4)(0.5)
