EXTRACTION AND CHARACTERIZATION OF CHITOSAN FROM GIANT AFRICAN LAND SNAIL’S SHELLS
AbstractChitosan, a biopolymer derived from chitin, has garnered significant attention due to its unique properties, eco-friendly nature, and diverse applications in various industries owing to its remarkable properties. This study focuses on the extraction and characterization of chitosan from giant African snail shells. Various experiments were designed to optimize the extraction process, resulting in a chitosan yield of 61.37%, a moisture content of 2.02%, and a degree of deacetylation (DD) of 68.24%. The physicochemical properties of the extracted chitosan nanoparticles were characterized, revealing important parameters for its potential applications. Fourier Transform Infrared Spectroscopy (FTIRS) analysis indicated the presence of functional groups such as O-H, N-H, C≡C, C=C, and N-H bending, corroborating previous studies. Scanning Electron Microscopy (SEM) revealed the chitosan particles’ polygonal shape and rough surface, suggesting their suitability for adsorption applications and heavy metal trapping. X-ray Diffraction (XRD) analysis demonstrated a semi-crystalline nature of the chitosan, with a sharp peak at 34° (2θ) and other suppressed peaks. These findings confirm the successful synthesis of chitosan from giant African snail shells and highlight its potential for various applications, supported by its favorable physicochemical properties.
