Hydroxyapatite (HAp) Ca10(PO4)6(OH)2 is a calcium phosphate-based mineral that
acts as bio-ceramic material and widely applied in several industries. In present study,
HAp was extracted from shortfin scad (Decapterus macrosoma) bones due to its
abundance from the processing industries. HAp from shortfin scad bones is preferred
as it helps to reduce the abundance of bio-waste. This study was aimed to examine
optimum condition for the extraction of HAp from shortfin scad bones and to
characterise their physico-chemical properties. The cleaned bones were heated at
temperatures ranged from 600°C to 1000°C. The highest yield for optimum
temperature was found at 50.75%. The synthesized HAp has been characterized by
Fourier Transform Infrared Spectroscopy (FT-IR), X-ray Diffraction (XRD), and
Scanning Electron Microscopy (SEM). Findings showed that synthesized HAp exhibited
similar characteristics compared to commercial HAp. Overall findings suggested that
HAp can be potentially commercialized from the shortfin scad bones.
