Fenton process in dispersed systems for industrial wastewater treatment
(Savez hemijskih inženjera, Beograd, 2019)
Industrial wastewater contains recalcitrant organic compounds with a very complex chemical structure, built of molecules with long chains of carbon atoms and attached different functional groups. Chemical or biological ...
Kiselo luženje oksidno-sulfidne rude bakra pre flotacije - način za povećanje iskorišćenja metala / Acid leaching of oxide-sulfide copper ore prior the flotation: A way for an increased metal recovery
(Savez hemijskih inženjera, Beograd, 2015)
Rudnik bakra Bor, lokalitet Cerovo, sadrži više rudnih tela koja sadrže značajnu količinu oksidnih minerala bakra u svojim površinskim slojevima (> 40%). To su najvećim delom karbonatni minerali, uz nešto kuprita i hrizokole, ...
Synthesis of alpha-al2o3 based foams with improved properties as catalyst carriers
(Institute of Metals and Technology, 2014)
This paper explores the possibility of synthesising catalyst supports with improved properties. Alumina foams were produced with the polymer replication technique. Representative high- and low-temperature sintering ceramics ...
Influence of clay organic modifier on the morphology and performance of poly(epsilon-caprolactone)/clay nanocomposites
(Srpsko hemijsko društvo, Beograd, 2015)
Two series of poly(epsilon-caprolactone) poly(oxepan-2-one) nanocomposites with different organo-modified clays (1 to 8 wt. %) were prepared by the solution casting method. Organoclays with polar (Cloisite (R) C30B) and ...
Assessment of lipophilicity of some biologically active arylpiperazines by rptlc and multivariate analysis
(Taylor & Francis Inc, Philadelphia, 2014)
The chromatographic behavior of arylureas and arylacetamides derivatives with observed biological activity toward dopamine D-2 and 5-hydroxytryptamine 5HT(1A) receptors were examined by high-performance thin-layer ...
Optimization of process parameters to obtain NH4-clinoptilolite as a supplement to ecological fertilizer
(Mineralogical Soc, Twickenham, 2014)
The application of natural fertilizer mixtures that improve nutrient retention ability of soils has attracted considerable attention in recent years. In addition to rock phosphate (RP), the basic components of these mixtures ...
The influence of melting atmosphere and casting on the mechanical and structural characteristics of palladium-nickel alloy
(National Institute of Optoelectronics, 2014)
The main aim of the research, presented in this paper, is to analyze the structural conditions of the PdNi5 alloy depending on the applied melting atmosphere and casting, as well as monitoring changes in the structural and ...
