4 | Description | Abstract | Carbonated hydroxyapatite /CHS nanocomposites of varying composition for biomaterial applications have been synthesized. The Carbonated hydroxyapatite /CHS nanocomposite materials were characterized by XRD, FTIR, FESEM, EDAX, HRTEM and XPS. Carbonated hydroxyapatite (CHAp) nanorod embedded composite was prepared using chitosan (CHS) as a matrix with different weight percentages (wt %). The results indicated that the size and crystallinity of CHAp nano particles decreases with increase in CHS concentration in the composite. FESEM confirms the presence of CHAp nanorod crystals in CHS matrix. Cyclic voltammograms (CVs) were recorded to evaluate the electrocatalytic behaviors of the modified electrode towards the oxidation of 4-NP in the potential range of 0 to +1.0 V. A glassy carbon electrode was modified with carbonated hydroxyapatite nanopowder (CHAp-NP) and characterized in terms of electrochemical oxidation of 4-nitrophenol (4-NP) via cyclic voltammetry. The catalytic reaction facilitates electron transfer between 4-NP and the modified electrode, as a result the electrochemical oxidation of 4-NP becomes easier. The reason for this is that the CHAp-CHS 80 can act as a promoter to increase the rate of electron transfer, lower the overpotential of 4-NP at the bare electrode, and the anodic peak shifts less positive potential. Thus, it is clear that CHAp-CHS 80 modified GCE can be successfully used for the determination of organic pollutant. |
