SYNTHESIS AND CHARACTERIZATION OF NANOCRYSTAL CELLULOSE DERIVED FROM Parkia biglobosa POD
Summary
Researchers synthesized and characterized nanocrystalline cellulose (NCC) from Parkia biglobosa pod waste using standard isolation procedures, confirming its structure via FTIR, SEM-EDX, XRD, TGA, and DTG analysis and finding that NCC exhibited higher crystallinity and greater thermal stability than raw pod powder, suggesting potential as a reinforcing agent for green composites.
The careless dumping of agricultural waste in Nigeria is a significant environmental issue that requires attention. Some states in Nigeria haphazardly dump the pod of Parkia biglobosa, a pod that should have served an essential purpose in the waste to wealth context. The study investigates the synthesis and characterization of nanocellulose derived from the Parkia biglobosa pod. Standard procedures were used to isolate nanocellulose and were characterised with FTIR, SEM-EDX, XRD, TGA, and DTG techniques. The FTIR analysis identified the existence of O-H, C-O-C pyranose rings, and cellulose ?-glycosidic connections. The SEM showed a surface that was uneven and had small clusters of the NCC. The devolatilization of cellulose in the raw and NCC of ALBP was recorded at 43.205% and 71.90%, respectively, with the NCC exhibiting the highest value. At 380?C and 400?C, the thermal decomposition peaks for raw Parkia biglobosa and NCC caused the most weight loss. Nanocrystal cellulose has a higher crystallinity index than raw pod powder. Using EDX, the elemental analysis revealed the presence of raw C (49.21%) and O (50.79%), while the NCC contains C (46.03%) and O (53.93%). with some variations. Various treatments applied to the raw locust bean pod correlate with the change in percentage mass. Thus, the NCC might be employed as a reinforcing ingredient for the creation of green composites, binder, adsorbents, and polymeric polymers.
