Effect of synthesis parameters on polymethacrylic acid xerogel structures and equilibrium swelling
(Maik Nauka/Interperiodica/Springer, New York, 2009)
Hydrogels based on crosslinked polymethacrylic acid were synthesized via free-radical polymerization in aqueous solution, using N,N'-methylene bisacrylamide as a crosslinking agent and 2,2'-azobis-[2-(2-imidazolin-2-yl)propane] ...
Treatment of highly contaminated waste waters in a continuous cascade line reactor
(World of Metallurgy - Erzmetall, 2007)
This paper presents research work done on complex copper bearing effluents from the Serbian RTB-Bor plant. The INTREAT project, funded by the European community, addresses environmental pollution problems associated with ...
Hydrogenation of oil produced by naphtha steam pyrolysis: Determination of catalyst activity / Hidrogenovanje pirolitičkog ulja nastalog u procesu pirolize primarnog benzina - određivanje aktivnosti katalizatora
(Association of Chemical Engineers of Serbia, 2000)
Residual pyrolysis oil (RPO) produced as a by-product of naphtha steam pyrolysis was hydrogenated (160-280°C; 60 bar; trickle-bed reactor with Co-Mo/y-AlgOs) with the aim of suppressing the polymerization of the unsaturated ...
Semi-Interpenetrating Networks Based on Poly(N-isopropyl acrylamide) and Poly(N-vinylpyrrolidone)
(Wiley, Hoboken, 2009)
Three series of novel semi-interpenetrating polymer networks, based on crosslinked poly(N-isopropylacrylamide), PNIPA, and different amounts of the linear poly(N-vinylpyrrolidone), PVP, were synthesized to improve the ...
Characterization of sepiolite by inverse gas chromatography at infinite and finite surface coverage
(Elsevier Science Bv, Amsterdam, 2009)
The adsorption properties of sepiolite from Andrici, Serbia, were studied by inverse gas chromatography at zero and finite surface coverage between 483 and 513 K. The thermodynamic parameters (free energy, enthalpy, entropy) ...
