Abstract:The study was carried out to investigate the bleaching efficiency of chitosan for pigments removal from palm kernel oil (PKO). Chitosan was synthesized from periwinkle shell waste by chemical technique involving demineralization, deproteinization and deacetylation. The bleaching was carried out (batch process) at various adsorbent dosages (1.0-3.0 g). The bleaching adsorbents (Periwinkle Shell Powder, PSP and chitosan periwinkle shell powder, CPSP) were characterized using X-ray fluorescence (XRF) for their el… Show more
