Abstract:The optimized process for cellulose extraction from oil palm empty fruit bunch (EFB) consisting of acid pretreatment (0.5% (v/v) H2SO4), alkaline extraction (15% (w/w) NaOH), and chlorine-free bleaching (10% (w/v) H2O2) yielded pulp with the highest cellulose content at 83.42%. The EFB cellulose was then etherified into carboxymethyl cellulose (CMC) which was readily water-soluble (81.32%). The EFB CMC (2.5% (w/v)) was blended with glycerol (0.5 % (w/v)) to produce a composite film by a solution casting method… Show more
