| Summary: | The
electrolysis method for synthesizing hydroxyapatite nanoparticles (NPs) has the
advantage of controlling the particle size by adjusting the potential and
current used. This study aims to study the electrolysis of hydroxyapatite NPs
formation and its characteristics. The solution contained Na2H2EDTA.2H2O,
KH2PO4, and CaCl2, with an EDTA/PO43-/Ca2+
concentration of 0.2/0.2/0.2 M. The electrolytic potential are 4, 5, and 6
volts for 6 hours. The carbon electrode spacing used is 2 cm. The precipitate
formed is filtered with a vacuum jet ejector. Retentate was washed with
demineralized water and dried in an oven at 105oC. The synthesis of pure
hydroxyapatite by electrolysis was successfully carried out at a potential of 5
volts. The OH- ion, which comes from the H2O reduction
process at the cathode, is essential in the formation of brushite, which then
forms hydroxyapatite. The hydroxyapatite, synthesized at a potential of 4
volts, had the smallest particle size (442.4 nm) with the largest particle
surface area (417.22 m2/gram). |
