Spanish Poplar Biomass as a Precursor for Nanocellulose Extraction

The effect of acidic hydrolysis duration on nanocellulose size, morphology, and proper ties was investigated, which opens up a whole new horizon versatility in poplar applications. This study aimed to examine Spanish wastes as raw material extract crystalline (CNC), substantiates the importance wastes. Wastes were pulped using 1 L 10% NaOH (wt./wt.) solution, bleached several times by NaClO2; afterwards, white subjected 60% H2SO4 for either 5, 10, or 15 min. Microcrystalline cellulose (MCC) underwent similar protocol control. TEM, IR, XRD characterization techniques performed. Poplar based sized 219 nm length 69 width after min hydrolysis. MCC yielded 122 12 crystals 10 Hydrolysis resulted drastic change intense peaks at 3500 2900 cm?1 nanocellulose. Although pre-hydrolysis fiber treatment not influencial crystallinity poplar, remarkably raised index (CI) 7–8%. more prolonged, size resulting crystal (whisker) decreased, aspect ratio increased. impactful than poplar. However, future work, it seems that longer pulping bleaching could have significantly removed unwanted components (hemicellulose lignin), showcased IR XRD, hence smoothened following
