Kinetika dobijanja biološki aktivnih anestezijskih vlakana / Kinetics of obtaining the biologically-activated fibers with anestheticactivity
(Loznica : Viskoza, 1999)
Biološki aktivna anestezijska vlakna se koriste za lokalnu anesteziju po pravilu u postoperativnom periodu. Dobijaju se hemisorpcijom anestezijskih medikamenata različitim katjonizmenjivačkim vlaknima.
U ovom radu proučavana ...

Copper Separation from Aqueous Effluents by Liquid Membrane Pertraction
(International Ecological Congress, Voronezh, Russia, September 22-28, 1996)
In this paper the feasibility of applying liquid membrane pertraction to the copper
recovery from aqueous effluents has been examined. A continuos laboratory-scale
hollow fiber-in-fiber type membrane pertractor was ...
Recovery of Indium in a Hollow Fiber Membrane Pertractor
(International Ecological Congress, Voronezh, Russia, September 22-28, 1996)
In the present work, the recovery of indium from sulfate media using a continuos-type membrane
pertractor with hollow fiber geometry was investigated as a study of the feasibility of the industrial
