Kristalisanje koncentrovanih rastvora celuloze u N-metilmorfolin-N-oksidu / Crystallization of concentrated cellulose solutions in N-methylmorpholine-N-oxide
(Loznica : Viskoza, 1992)
U istraživanju mogućnosti dobijanja hemijskih celuloznih vlakana bez upotrebe ugljen disulfida posebna pažnja je posvećena takvim direktnim rastvaračima celuloze kao što su tercijerni amini. U ovom radu proučavane su pojave ...
Reološka i druga svojstva N-metilmorfolin-N-oksidnog rastvora celuloze za vlakna / Rheological and other properties of cellulose solution in N-methylmorpholine-N-oxide
(Loznica : Viskoza, 1992)
Između različitih rastvarača za direktno rastvaranje celuloze i primene ovih rastvora za proizvodnju hemijskih celuloznih vIakana najperspektivniji je N-metilmorfolin-N-oksid (NMMO). Teižište ovog rada je na istraživanju ...
Savremeni trendovi u proizvodnji i primeni vlakana u svetu i sirovinska baza tekstilne industrije SRJ / New trends in production and application of fibres in the world and the raw material basis of Yugoslavian textile industry
(Savez inženjera i tehničara tekstilaca Srbije, 1998)
Posle velike ekspanzije u 1994. god., svetska proizvodnja hemijskih vlakana (sintetizovanih, celuloznih) u 1996. god. zabeležila je porast sličan ranijim godinama. Svetska proizvodnja hemijskih vlakana u 1996.god. porasla ...
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
application of this ...
Oxygen reduction on iron-V. Processes in boric acid-borate buffer solutions in the 7.4-9.8 pH range
(Pergamon-Elsevier Science Ltd, Oxford, 1991)
O2 and H2O2 reduction was studied on Puratronic iron (99.995%) in borate buffer solutions of various pH ranging from 7.4 to 9.8. In solutions of pH < 9.3 the E-j curves are of quite irregular shapes and the limiting ...
Oxygen reduction on iron-IV. The reduction of hydrogen peroxide as the intermediate in oxygen reduction reaction in alkaline solutions
(Pergamon-Elsevier Science Ltd, Oxford, 1991)
The kinetics of hydrogen peroxide reduction were studied on iron in borate buffered and unbuffered solutions of pH ranging from 8.6 to 13.8, with and without the presence of chloride ions. A rotating disk electrode was ...
