Abstract

Abstract. Fish bone contains about 62.31% CaO and 37.46% P2O5 so that it can be used as hydroxyapatite material. This composition is also contained in the bone of the broom fish (Hypostomus plecostomus) which is known from the XRF test. Therefore, the purpose of this study was to determine the phase and functional group of hydroxyapatite from broomstick fish bones. Synthesis of hydroxyapatite from broomstick fish bones using the precipitation method, namely as much as 7 grams of CaO dissolved in 100 ml of distilled water and heated at 90°C then added 100 ml of 0.6 M H3PO4 to obtain a clear solution. Then the solution was added with 1 M NaOH until it reached pH 10, allowed to stand for 24 hours and a precipitate was formed. After that, it was heated at a temperature of 900°C with a holding time variation of 5 hours and 7 hours and then cooled at room temperature. The results of this synthesis were characterized by XRD and FTIR. Based on the XRF results, the broom fish bone has a CaO content of 81.37%. The main phase of hydroxyapatite was formed optimally at a holding time of 7 hours and had a crystal size of 32.39 nm which was calculated based on the Scherrer equation. FTIR results show that hydroxyapatite consists of three main functional groups, namely phosphate , hydroxyl (OH-) and carbonate in the wave range of 4000 cm-1 – 500 cm-1. Thus, in this study, hydroxyapatite from broom fish bones was successfully synthesized. Keywords : Hydroxyapatite, CaO, broom fish bone, Precipitation.
