Synthesis and characterization of cellulose nanocrystals extracted from sago (Methoxylon sagu) pulp

Sago (Metroxylon sagu) pulp is a common agricultural product; however, its (from the main plant part and bark) finds no essential use considered waste. In this study, cellulose nanocrystals (CNCs) were isolated from bark of sago through bleaching, alkali treatment, acid hydrolysis. The hydrolysis was performed with 64% (w/w) sulfuric acid. A considerable yield obtained for extracted CNCs, 65.36% (SMP), 77.43% (SBP), which are comparable to other previous reported protocol. FTIR analysis resulting CNCs showed similar vibration frequencies α-cellulose. Concerning spherulites, size reduction revealed in Scanning Electron Microscopy (SEM) after α-cellulose obtain CNCs. Importantly, an image Transmission Microscope (TEM) bundles needle-like structure characteristic Thermogravimetric (TGA) also stability Elemental via EDX that two forms nanocellulose derived possessed mostly carbon oxygen. small amount (3-8%) attributed degradation α-cellulose, may have been caused by alternative bleaching process employed. Despite this, reasonably good percent extracted, demonstrating pulp's potential as useful source cellulosic nanomaterial.
