2020年1月15日 · The thermo gravimetric analysis (TGA) plots recorded from the bovine bone samples in different parts (Fig. 1) show three distinctive weight loss stages. The weight loss rate is relatively low at pyrolysis temperatures of <300 °C (the first stage) owing to the evaporation of volatile substances, primarily the moisture contained in bones.

By pyrolysis or gasification, waste bones can be converted into bone char (BC), which can be used as an adsorbent for removing pollutants from wastewater and effluent gas.

2024年12月6日 · The catalytic behavior of bone char modified with chlorosulfonic acid is tested as reusable and eco-friendly solid acid biocatalyst in synthesis of pyrimidine-5-carbonitrile derivatives.

2022年8月19日 · Thermal degradation products correlated to a particular temperature or range of temperatures can provide clues about composition and bonding in complex materials like bone char. Using TGA-MS, thermally-induced chemical changes can then be correlated to the temperature range over which they occurred and related to the weight lost over that range.

2015年12月1日 · In this study, bone char was obtained by pyrolysing bovine and bull bones. The physical and chemical properties of the bone char has been investigated in detail using a number of characterisation techniques. The 400–600 °C temperature range with two varied residence time (1 and 2 h) was considered for bone char synthesis. The results ...

By pyrolysis or gasification, waste bones can be converted into bone char (BC), which can be used as an adsorbent for removing pollutants from wastewater and effluent gas.

The characterization of the bone char was performed by X-ray diffraction (XRD), attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR), and scanning electron microscopy...

Bone char is generally comprised of 70-76% Ca 10 (PO 4 ) 6 (OH) 2 , 7-9% CaCO 3 , and 9-11% amorphous carbon [15]. Ca 10 (PO 4 ) 6 (OH) 2 , namely hydroxyapatite, is an advantageous material to...

2022年3月22日 · In this study, bone char pretreated with hydrogen peroxide and traditional pyrolysis was applied to remove Cd2+ from aqueous solutions. After hydrogen peroxide pretreatment, the organic matter content of the bone char significantly decreased, while the surface area, the negative charge and the number of oxygen-containing functional groups on ...
