Cellulose nanocrystals (CNC) receive great attention for their physical and optical properties, high surface area, high tensile strength, rigidity (Young's modulus up to 140 GPa), and ease of surface modification. However, controlling the properties of CNC is still challenging, given the wide variety of pulp sources and the complexity of finding suitable processing conditions. In the present study, acid hydrolysis efficiently isolated CNC from wood brown kraft pulp (AMKP).

- Tannins, natural compounds from plants, can be a sustainable option for treating wastewater, especially when modified to reduce their solubility in water.
- New methods have been developed to bind tannins to nanocellulose, creating adsorbents that effectively capture pollutants like copper (Cu II).
- The study found that using glutaraldehyde for immobilization significantly decreased tannin leaching and confirmed that these adsorbents work quickly and steadily to remove contaminants from water, suggesting a promising eco-friendly solution for effluent treatment.
In this study, a strategy was adopted to enhance the use of ramie fibers as raw material for isolation of cellulose nanofibers (CNFs). Ramie pulp was produced by alkaline organosolv followed by bleaching. CNFs were produced by mechanical defibrillation, and films were fabricated via casting.
