Effects of pre and post-ozonation on pofa hollow fibre ceramic adsorptive membrane for arsenic removal in water
This study examined the use of modified palm oil fuel ash (POFA) prepared from agricultural waste as key material for fabricating the POFA hollow fibre ceramic membrane (PHFCM) to trap arsenite, As(III), and arsenate, As(V), from water. In this study, the ozonation technique was employed where the e...
