Abstract:
Polyamide (PA 66) membranes were prepared via phase inversion with immersion precipitation from mixtures of acid formic as solvent, polyvinylpirrolidone (PVP) and ammonium oxalate (OX) as constant additives and formamide and water as variable additives. The pure water was employed as non-solvent. The influences of additives in the casting solution on structure and permeation properties of the membranes were
analyzed by scanning electron microscopy (SEM) and separation experiments.
