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 ...
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 ...
