Preparation of nanofiltration hollow fiber membrane for acetic acid removal from synthetic hydrolysate

Nanofiltration has a pore size range of 0.001-0.01um. NF membranes can filter particles up to and including some salts, synthetic dies and sugars, however it is unable to remove most aqueous salts and metallic ions, as such, NF is generally confined to specialist uses. Nanofiltration (NF) is a promi...
