Feasibility study of pineapple (Ananas cosomus) leaf fibres (PALFs) for cellulosic microfiltration membrane / Nor Aida Zubir … [et al.]

The study was conducted to investigate the possibility of using pineapple leaf fibres (PALFs) as an alternative source of cellulose polymer for membrane fabrication. The membranes were fabricated from dope solution containing cellulose/ N-methylmorpholine-N-oxide (NMMO)/polyethylene glycol (PEG 400)...
