Benzoio aoid

The membrane material strongly influences the effect of US energy on filtration. Water permeation through a polyacrylonitrile (PAN) membrane from a dextran [96], that of NaCI through a nylon membrane coated with amphiphiles [97], the transport of organic compounds aoross a polymer membrane suspension, and that of hydrocortizone and benzoio aoid through a cellulose membrane and poly-dimethylsiloxane membrane, respeotively [98], illustrate the influence of the membrane material on the type of particles it can retain optimally.
