Abstract

UV-assisted photochemical technique was used to produce modified polysulfone (PS) membranes and their separation ability of natural pigments from rose petal extract was tested. Grafting by hydrophilic monomer (acrylic acid) increased wettability of polysulfone membrane surface and shifted the membrane to lower molecular weight cut off, which increased retention in anthocyans from rose petal extract. Membrane modified with acrylic acid with different grafting showed gradual increase in performance behavior towards the anthocyans separation. The pH dependence performance study showed different significant behavior in anthocyans separation, as the chemistry of modified membranes and anthocyanins is sensitive.
