Bovine bone waste can be used for grafting, repairing, replenishing or replacing bones and restoring dental tissue. The purpose of this research is to determine whether the content of the coffee grounds and shellac will disappear after the sintering process, and how the effects of coffee grounds on the porosity and degradation rate of BHA biocomposite materials. This research uses heating method of calcination and sintering. Based on the analysis of test data conducted, it was concluded that SEM EDX observation shows the presence of inorganic elements of Ca and P with high intensity and Na, Mg, O and C with low intensity. Observation of XRD diffraction pattern shows 2θ values of the sample according to the standard diffraction pattern of HA JCPDS 9-432. FTIR functional group analysis showed no major peak points other than phosphate fu...

The result showed that the adsorption was optimum at pH 5 and contact time of 250 min. Adsorption of Pb(II) ion with all of adsorbents followed pseudo-second order kinetic equation. Adsorption of Pb(II) ion on CTS followed Freundlich isotherm while that on NIP and Pb-IIP followed the Langmuir adsorption isotherm. The adsorbent of Pb-IIP give higher capacity than the NIP and CTS. Adsorption capacity of Pb-IIP, NIP and CTS were 167.1, 128.9 and 76.1 mg/g, respectively.
