    Filtering PVA-coated microparticles

    Victoria I posted a topic in Organic Chemistry
    Hi, I am currently working on a project where I am filtering out small (<0.45 um) polymer microparticles that are slightly hydrophyllic because of the polyvinyl alcohol used as an emulsifier. I'm trying to find the best filter material to use so that if I passed water through the opposite side of the filter, I could recover the particles that were too big to pass through. My options are polyether sulfone, surfactant-free cellulose acetate, Nylon, and cellulose nitrate. Any suggestions?
