Sol Gel Assisted Microwave Synthesised Hydroxyapatite Nanostructure using Biowaste Musselshell as A Calcium Source

The common waste material from fish industry is Mussel shells which is normally disposed in land areas. The main composition of mussel shells is Mussels and aragonite. Hence it is considered as a by-product for producing nanomaterials. Nano Hydroxyapatite (n-HAp, Ca10(PO4)6(OH)2) has been prepared by microwave irradiation method using Mussel shell and Orthophosphoric acid as precursors at normal room temperature. Powder XRD results suggest that HAp are found to be hexagonal, P63/m symmetry, well matched with JCPDS card no: 09-0432. Restriction of particle growth was due to the substitution of capping agent EDTA while precipitation. FTIR predicts the presence of C-O and P-O stretching. The characterized sample is uniformly distributed, crystalline and elongated in nature. The morphology was identified to be spherical shaped by SEM micrographs with diameter of around 40 – 32 nm. EDAX reveals that it has standard Ca/P ratio 1.6. TEM reveals rod shaped Morphology.
