Fabrication and characterisation of ceramic hollow fibre membrane from metakaolin and corn cob ash for oil–water separation

Oily wastewater discharged into the environment causes serious global water pollution issues, which necessitates emerging recovery technologies, such as membranes for water purification. In this study, ceramic hollow fibre membrane (CHFM) derived from abundant waste materials of metakaolin (MK) and...
