Surface modification of polyethersulfone membrane via uv-grafting for forward osmosis technology = Modifikasi permukaan membran polyetersulfon melalui cantuman-uv untuk teknologi osmosis ke hadapan

In this study, UV-grafting was used in surface modification of polyethersulfone membrane (UFPES50) for forward osmosis (FO) application. Using two parameters, namely monomer concentration (acrylic acid) and grafting time, the modified membrane was characterised by attenuated total reflectance-Fourie...
