Abstract
Tannins, which are water-soluble polyhydroxyphenols found in plant structures, offer a sustainable alternative to inorganic products for treating effluents. To overcome their solubility in water, new methods have been developed to immobilize tannin on materials such as nanocellulose, resulting in tannin-based adsorbents. This study investigates the production of different types of tannin-based adsorbents immobilized on nanocellulose nanofibrils using glutaraldehyde as a crosslinking agent. The adsorbents were characterized for their morphology, chemical composition, tannin leaching, thermal stability, and copper adsorption capacity. The main results showed that tannin leaching from the adsorbents in water was greatly reduced with glutaraldehyde. Scanning electron microscopy images showed tannin coating on the surface of nanocellulose nanofibrils due to immobilization. The lyophilized adsorbent was effective in adsorbing Cu (II) within 1 min, with the adsorbed amount increasing gradually until stabilization after 45 min. Overall, this study suggests that tannin immobilized on nanofibrillated cellulose has the potential to offer a sustainable and renewable alternative for effluent treatment.

Abstract
This work describes the production/characterization of low molar mass chitosan nanoparticles derived from waste shrimp shells (SSC), as well as from a commercial chitosan (CC). The production of low molar mass nanochitosan employed thermal shock, alternating between 100 °C and ambient temperature, followed by grinding the dry material (SSC and CC) in a ball mill, producing around 500 g of nanochitosan per batch. A highlight of the methodology employed is that it enables nanochitosan to be obtained even from a low quality commercial raw material. All particles had diameters smaller than 223 nm, with an average diameter below 25 nm (determined by DLS), while reductions of molar mass were between 8.4-fold and 13.5-fold. The depolymerization process resulted in a reduction in crystallinity of 38.1 to 25.4% and 55.6 to 25.9% in the CC and SSC samples, respectively. The production of nanochitosans was also confirmed by TEM through the observation of crystalline domains with diameters between 5 and 10 nm. This work perfectly reproduces the results on bench scale from previous research. The simple and inexpensive processes enable easy scale-up, representing an important advance in the production chain of biopolymers. Graphical abstract.
