ANALISIS HIDROKSIAPATIT DARI TULANG IKAN TUNA (THUNNUS ALBACORES) DENGAN XRF, FTIR, dan XRD

St Chadijah

Abstract


Hydroxyapatite (Hap) with molecular formula Ca5(PO4)3OH is calcium apatite bioceramics which can be found in human teeth and bones. This material is synthesized through a hydrothermal process with calcium precursors derived from fish bones yellow fin tuna (Thunnus albacores) and phosphate precursor NH4H2PO4 0.547 M. On research conducted long stirring time variation and its effect on rendemen and the resulting crystallites products. As for the variation of the long time of stirring used are 1, 2, 3, 4 and 5 hours. The optimum time of formation of hydroxyapatite obtained within 3 hours stirring from which content was 96.4156%. The material was analyzed by FTIR and XRD. Results showed their characterization by FTIR absorption carbonate groups (CO32-) at wave number 1400-2400 cm-1, a phosphate ion (PO43-) at wave number 500-1050 cm1- and hydroxyl ions (OH-) at wave number 3500 cm-1. It is from XRD analysis, that size and the shape of the crystal which was obtain within 2 hours of stirring are 41,9753 nm and hexagonal.
