Synthesis, characterization and evaluation of physico-chemical profile of Cu-Chitosan Nanocomposite


Author(s): Manju Kumari Choudhary, Swati and Vinod Saharan

Abstract: In this paper, we have synthesized stable and monodisperse Cu-chitosan nanocomposites (NCPs) based on the ionic gelation of chitosan with tripolyphosphate anions and Copper ions. The physicochemical properties i.e. particle size (295.4 nm), polydispersity index (0.28), zeta potential (+ 19.6 mV), functional group analysis (chitosan, TPP and Cu interaction by frequency distribution), shape (sphere), morphology (highly porous), elemental composition (C,O,P,N and Cu) were characterized by Dynamic light scattering (DLS), Fourier transforms infrared (FTIR), Transmission electron microscopy (TEM), Scanning electron microscopy (SEM) and SEM energy dispersive X-ray spectroscope (SEM-EDS). Further, release profile of metal elements in Cu-chitosan NCPs was studied by atomic absorption spectroscopy (AAS) under varying pH, agitation period and agitation rate. The objective of this study was to solve the problem of preparation of Cu-chitosan NCPs with high degree of monodispersity and stability and investigate the effect of various parameters on the release profile of metal elements in Cu-chitosan NCPs.
