(Serbian Chemical Society, Belgrade, 2002)
The interactions of n-hexane, benzene, chloroform, and tetrahydrofuran with dried (amorphous) chromia (I) and chromia heated at 1073 K (crystalline) (II), both obtained from a colloidal dispersion, and a commercially ...
Development of ion chromatography methods for the determination of trace anions in ultra pure water from power plants / Razvoj metoda jonske hromatografije za određivanje tragova anjona u ultra čistim vodama iz termoelektrana
(Serbian Chemical Society, Belgrade, 2005)
A suppressed ion chromatography (IC) technique, using a carbonate/hydrogen carbonate or a hydroxide eluent, has been evaluated as a monitoring tool for the detection of major anions (F-, Cl-, NO3-, PO43- and SO42-) in ultra ...
An experimental study of the partial oxidation of ethane to ethylene in a shallow fluidized bed reactor / Eksperimentalno ispitivanje parcijalne oksidacije etana do etilena u reaktoru sa plitkim fludizovanim slojem
(Serbian Chemical Society, Belgrade, 2007)
The partial catalytic oxidation of ethane to ethylene was investigated experimentally in a shallow fluidized bed. The performances of two catalyst types, pure γ-Al2O3 and V2O5/γ-Al2O3 particles 1.8 mm in diameter, were ...
