[Display omitted] In this study, a sponge-like nanocomposite ceramic was made of clay, bovine bone nano-powder, and human hair; to remove Ni(II) and Co(II) ions from synthetic and industrial wastewaters. The structure of sponge-like nanocomposite ceramic was investigated with XRD (Hexagonal structural type of hydroxyapatite) and functional groups were identified using FT-IR (Hydroxyl @ 3573 c m - 1 and Phosphate @ 1045 c m - 1 ). The specific surface and morphology of the ceramic-based on BET (172.46 m 2 g - 1 ) and FE-SEM (Nano-hydroxyapatite: 100 nm), respectively showed that the use of human hair creates good porosity. The process was optimized at pH 6, temperature 40 ℃, adsorbent mass 17 g, initial concentration iofns 233 mg L −1 , and retention time 178 m i n. Kinetic models, thermodynamic parameters and, isotherm models were applied to describe the adsorption equilibrium data. The Ni(II) and Co(II) adsorption efficiency, from industrial wastewaters, were more than 95%. The adsorbents could be regenerated and reused for up to 60 consecutive cycles. [ABSTRACT FROM AUTHOR]
