The F- adsorption capacity of cattle bone biochar (CBB) modified with by Fe2(SO4)3, Al2(SO4)3, and Al2(SO4)3 and Fe2(SO4)3 composite was investigated. Results showed that the adsorption capacity of CBB modified with Fe2(SO4)3 and Al2(SO4)3 composite (Fe-Al-CBB) reached 45.45 mg/g, which was 8.5 times the adsorption capacity of unmodified CBB (5.34 mg/g). The adsorption data were well fitted to the pseudo-second-order kinetic model for raw and modified CBB. The adsorption isotherm is more consistent with the Langmuir isotherm adsorption equation. The order of point of zero charge found is that of Al-Fe-CBB > Al-CBB > Fe-CBB > CBB, which was 7.47, 7.20, 6.62 and 6.19, respectively. The highest removal efficiency of F- of Fe-Al-CBB, Al-CBB, Fe-CBB and CBB was 98.56%, 74.77%, 20.95%, and 11.57%, respectively. The higher removal efficiency of F- of Fe-Al-CBB was related to its higher zero charge point. Results suggest that the Al2(SO4)3 and Fe2(SO4)3 composite modified CBB is a promising absorbent for removal of F- from water.
