Abstract An integrally skinned organic solvent-resistant membrane with asymmetric structure for solvent nanofiltration (OSN) application was developed via thermally induced phase separation (TIPS) of nanocomposite polyamide 6. The 6 contains intercalated silicate sheets, which could improve the mechanical properties resultant membrane, as well mitigate swelling after exposure in solvent. influe...

Composite Nanofiltration membranes were fabricated by incorporating Carbon Nanotubes (CNT) and Polyvinylidene Fluoride (PVDF) membranes. A suspension was prepared by dispersing CNT (30 minutes of sonication) in Dimethyl Sulfoxide (DMSO) solvent for 0.5 mg/ml. This suspension after vacuum filtration dispersed over PVDF membrane of pore size 0.22μm. Excess DMSO was removed by washing using Ethano...

A "sandwich" type polyoxometalate catalyst ([MeN(n-C8H17)3]12[WZn3(ZnW9O34)2]) was very efficiently recycled by nanofiltration with almost quantitative retention, using an alpha-alumina supported mesoporous gamma-alumina membrane.

Present study has been under taken to evaluate the nutraceutical significance of bioflavonoid naringin, from pummelo fruit peel. Bioflavonoids were selectively extracted from the pummelo fruit peel meal without any interference of pectin using aqueous ethanol as solvent. Significant naringin content of 0.440.02g/100g of peel was found in fruit peel meal. For selective fractionation and concent...
