Hydroxyapatite (HAp) synthesized from milkfish bones and scales was investigated
for its potential to remove hexavalent chromium (Cr6+) from water. The HAp was synthesized
through calcination at varying temperatures and characterized using FTIR, SEM, and EDS.
Optimal calcination temperatures were 700°C for fish scales and 900°C for fish bones,
yielding HAp with excellent crystallinity and significant carbonate and phosphate groups,
ideal for biosorption. The study evaluated adsorption efficiency under varying adsorbent
dosage, pH, and contact time conditions. Optimum removal efficiencies for Cr6+ were 34.99%
for fish bone HAp and 33.54% for fish scale HAp, with yields of 48.78% and 60.83%,
respectively. The adsorption process was exothermic, with decreased efficiency at higher
temperatures. Optimal conditions for maximum Cr6+ removal were identified as 1.0g
adsorbent dosage, pH 2, and contact times of 25 minutes for fish bone HAp and 60 minutes
for fish scale HAp. This research demonstrates the potential of using waste materials from the
fish processing industry for environmental remediation of heavy metal contamination. Further
studies are recommended to optimize the biosorption process for broader applicability.
