14: POLY(AMIDE-IMIDE)S 331
miscibility of 1,4-dioxane in the dope solution with
coagulant and higher water tolerance of the PAI allows
the preparation of membranes with a spongy substruc-
ture and the pore size of the blend membranes can
be controlled. The hydrophilicity of the poly(sulfone)
membranes can be improvedby the addition ofPAI and
TiO
2
nanoparticles. These components have a prefer-
ential orientation toward the membrane surface. These
prepared membranes are suitable for the separation of
humic substances from aqueous streams.
The fouling stability and the chlorine stability were
studied. As a model foulant, bovine serum albumin
was used. An impro ...
