摘      要：Cellulose,microcrystalline cellulose and nanocellulose were prepared from three agricultural waste resources:pineapple leaf(PALF),banana rachis(BR),and sugarcane bagasse(SCB).Each waste resource was first converted into microcrystalline cellulose which was subsequently converted into cellulose nanoparticles by using mild(30%w/v)and strong(60%w/v)sulfuric acid concentrations for *** transform infrared spectroscopy(FTIR),X-ray diffraction(XRD),and thermogravimetric analysis(TGA)were used to characterize each waste resource and extracted cellulosic ***,nanocelluloses were studied by zeta potential,size analysis,and transmission electron microscopy(TEM).Cellulose nanowhiskers were successfully obtained and isolated with a 33%average yield by applying a mild acid *** BR and SCB proved to be more promising agricultural waste resources in terms of their crystalline cellulosic content and properties.
