Determination of inorganic anions in papermaking waters by ion chromatography
(Journal of the Serbian Chemical Society, 2009)
A suppressed ion chromatography (IC) method for the determination of inorganic anions in process water from paperboard production was developed and validated. Common inorganic anions (Cl(-), NO(3)(-), PO(4)(3-) and SO(4)(2-)) ...
Synthesis, structure and solvatochromism of 5-methyl-5-(3-or 4-substituted phenyl)hydantoins / Sinteza, struktura i solvatohromizam 5-metil-5-(3- ili 4-supstituisanih fenil)-hidantoina
(Serbian Chemical Society, Belgrade, 2009)
Several 5-methyl-5-(3- or 4-substituted phenyl)hydantoins were prepared and their ultraviolet absorption spectra were recorded in the region 200-400 nm in twelve solvents of different polarity. The effect of solvent ...
Ethylene oxide removal by sorption on aluminium oxide / Uklanjanje etilen oksida sorpcijom na aluminijum oksidu
(Association of Chemical Engineers of Serbia, 2009)
The dynamics of ethylene oxide sorption and desorption on Al2O3 sorbent were investigated. The investigations of ethylene oxide sorption on Al2O3 show that significant sorption appeared above 125°C. The removal of sorbed ...
Effect of non-stationary current regimes on the morphology of silver electrodeposits / Efekat nestacionarnih strujnih režima na morfologiju taloga srebra
