Polymeric nanofiltration cellulose acetate (CA) membrane was prepared by phase inversion
method and effect of anionic surfactant on the membrane characteristics and performance was
investigated. The prepared membranes were characterized by several techniques including
scanning electron microscopy (SEM), atomic force microscopy (AFM), contact angle and zeta
potential measurements. 3,5-dinitrosalicylic acid (DNSA) was used as pesticide and experiments
were carried out at different solution pHs. The obtained results indicate that addition of SDS to CA
casting solution results in membranes with considerably thinner skin layer and higher porosity.
Moreover, the pure water flux, permeation and rejection of DNSA were improved significant
