Abstract

New nanofiltration membranes were produced in the form of unfilled fibers through the photopolymerization method. Parastyrene sodium sulfonate was used as the vinyl monomer to reform the poly sulphone ultra-filtration membranes. The modified membranes were used to purify colored solutions of three different pigments consisting acidic, reactive and direct (suitable for dyeing pile yams and warps), in order to refine and reuse the pigment solutions. The effect of various parameters like pressure, electrolyte, time, and the kind of pigment on the extent to which the pigment is confined and the flux of the membrane outflow was assessed. Results showed that besides the effective function of BLEACHING, the problem of barred pores observed in most commercial membranes built of polyamide also reduced significantly in the new membranes.
