Comparative Adsorption Performance of Carbon-containing Hydroxyapatite Derived Tenggiri (Scomberomorini) and Belida (Chitala) Fish Bone for Methylene Blue

The utilization of fishbone as the carbon source for methylene blue adsorption has been successfully studied. Fishbone was prepared from two kinds fish such marine fisheries (ex. Tenggiri) and freshwater Belida). carbons were by carbonation powder at 500 °C 2 h. Physical properties characterized using Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), wavelength dispersive fluorescence (WDXRF), Scanning Electron Microscope (SEM), hydrophobicity. utilized adsorbent removing varying contact time, initial dye concentration, temperature. It is concluded that both can very good adsorb blue. performance (TFC) Tenggiri better than (BFC) Belida fish. well fitted with Langmuir model (R2 ~ 0.998) pseudo-second-order model. This indicated molecules adsorbed on surface-active site via chemical binding, forming an adsorbate monolayer. Thermodynamic parameters, including Gibbs free energy (ΔG), enthalpy (ΔH), entropy (ΔS), onto spontaneous.
