Synthesis, characterization and antibacterial activity of cellulose acetate–tin (IV) phosphate nanocomposite

Cellulose acetate–tin (IV) phosphate nanocomposite (CA/TPNC) was prepared using simple method at 0–1 pH. The nanocomposite ion exchanger was characterized using some techniques such as Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD), and thermogravimetric analysis (TGA/DTA/DSC). The nanocomposite material was explored for different properties such as ion exchange capacity, pH titration, elution behavior, thermal stability, and distribution coefficient. The ion exchange capacity of CA/TPNC was found higher compared to their inorganic counterpart. The distribution coefficient studies of nanocomposite ion exchanger were investigated for different metal ions. On the basis of distribution coefficient studies CA/TPNC material was found more selective for Cd2+ and Mg2+. CA/TPNC ion exchange was explored for antibacterial activities against E. coli bacteria.
