“…Therefore, in our design, the levels of these factors were selected in wide ranges. According to the results of previous studies [19,20], annealing at 400°C was found to produce the materials with the best sorption properties. The treatment at this particular temperature was chosen as discontinuous factor, in order to compare the effect of thermal and chemical treatments and to detect their potential synergic effects.…”

“…The selection of process variables and their levels was made based on the survey of the literature concerning the effects of different treatments on sorption properties and applicability of bone produced materials [19,20,[22][23][24]. As the main process variables, the following five were considered: type and the concentration of the chemical reagent, reaction temperature, reaction time, and annealing.…”

“…The increase of specific surface area was found to be remarkable, however, 50 % of the overall value is accounted for carbon phase, which is less efficient and less selective cation sorbent than HAP. A systematic study on the influence of heating temperature (in the range 400-1000°C) on bone sorption properties was also performed [19,20]. Annealing at 400°C caused incomplete combustion of bone organic components.…”

Animal bones have been studied as a resource of low-crystalline apatite for immobilization of toxic heavy metals. Chemical and thermal treatments can be applied for selective removal of bone organic constituents. In this study, the impact of different treatment factors was determined by experimental design methodology, and comparison of the estimated effects was performed in order to optimize the treatment conditions. Fractional factorial design with five variables at two levels was applied for factors screening. The type of chemical reagent (H 2 O 2 or NaOH), its concentration (0.1 or 2 mol/L), reaction temperature (20 or 60°C), contact time (1 or 3 h) and sample annealing (without or at 400°C) were considered as process variables. Structural properties of bone sorbents, loss of ignition, point of zero charge, surface functional groups, specific surface area, chemical composition, and Cd 2? sorption efficiency, were selected as system responses. Samples significantly differed in respect to the organic phase content and composition, thus mechanisms of Cd 2? sorption were complex. Statistical analysis has revealed that, between all studied factors, temperature treatment was the most important for sorbents increased specific surface area, porosity and cation sorption. Furthermore, NaOH was more effective than H 2 O 2 , while the effects produced by variation of other factors were less pronounced. The highest proportion of bio-apatite with desired low crystallinity and high specific surface area was achieved by synergetic effects of chemical treatment with NaOH and thermal treatment at 400°C.

“…Heating in air atmosphere is one of the methods for decomposition of organic compounds. The influence of heating temperature on bone physicochemical and sorption properties has been investigated, and the optimal temperature was found to be 400 °C [15,18]. At lower temperatures organic phase was removed incompletely, while higher temperatures resulted in sintering of HAP nanoparticles and deterioration of sorption capacities.…”

Article Highlights • Apatite materials derived from bovine bones were studied as Ni(II) ions sorbents • Raw bones were compared with chemically, thermally and chemically/thermally treated samples • Different sorption mechanisms were identified by sorption data and FT-IR spectra analysis • Combined chemical/thermal treatment produced material with the highest sorption capacity • Sorbed Ni(II) was very stable at low sorbent loads, while largely mobile at high loadings
