Preparation of nanofiltration membranes and relating surface chemistry with potential and topography: Application in separation and desalting of amino acids

Nanoparticles modified Polyacrylonitrile/Polyacrylonitrile – Polyvinylidenefluoride blends as substrate of high flux anti‐fouling nanofiltration membranes

“…This phenomenon can be observed from SEM images (Figure 6) and also reflected in the pure water flux of the membranes. Using the equation r p = 0.045 × MWCO 0.44 45,46 the pore radius (r p ) of the NF membranes were calculated and presented in Table 2. It is observed from the table that NF2 series membranes are characterized by the highest pore size in comparison with the NF1 and NF3 series membranes which synchronizes with the observations of MWCO values.…”

NanoSiO2andTiO2embedded polyacrylonitrile/polyvinylidene fluoride ultrafiltration membranes: Improvement in flux and antifouling properties

“…[ 18 ] The mean pore size ( r p ) of the membranes was calculated with the aid of the equation r p = 0.045 × MWCO 0.44 and the results are shown in Table 2. [ 32 ] The mean pore size of virgin PAN and PVDF membranes are 14.73 and 7.13 nm, respectively. With 1% SiO 2 loading, the mean pore size decreases to 11.93 and 6.21 nm for PAN and PVDF membranes, respectively.…”

Nanofiltration membrane for bio‐separation: Process‐oriented materials innovation

“…By comparing the separation behavior of amino acids by four NF membranes, Ray et al. claimed that the NF membrane with highest negative Zeta potential exhibited significant differences in amino acid rejections at different pH, which might be suitable for the separation of amino acids from their mixture [24]. Using the NTR7450 membrane whose pore size is larger than the size of l ‐glutamine, Li et al.…”
