Conversion of biomass into biochar using different plant biomasses has been molded research towards the recycling of waste. Many approaches have been used for the fabrication of biochar at different temperature and pH ranges. Biochar has been characterized using advanced analytical tools like Fourier transform infrared Spectroscopy (FTIR), Raman spectroscopy, Scanning electron microscopy (SEM), Transmission electron microscopes (TEM), Thermogravimetric analysis/Differential thermal analysis (TGA/DTA), Energy dispersive X-ray (EDX) and X-ray diffraction analysis (XRD). Brunauer–Emmett–Teller (BET) explains the physical adsorption of gas molecules on the solid surface and uses measurement of the specific surface area of materials. Due to its vast surface area, biochar has been efficiently employed for the adsorption of heavy metal ions. The significant results of metal ions adsorption capacity revealed that biomass-driven biochar could be a better alternative for the removal and recovery of heavy metal ions from wastewater.

摘要

Conversion of biomass into biochar using different plant biomasses has been molded research towards the recycling of waste. Many approaches have been used for the fabrication of biochar at different temperature and pH ranges. Biochar has been characterized using advanced analytical tools like Fourier transform infrared Spectroscopy (FTIR), Raman spectroscopy, Scanning electron microscopy (SEM), Transmission electron microscopes (TEM), Thermogravimetric analysis/Differential thermal analysis (TGA/DTA), Energy dispersive X-ray (EDX) and X-ray diffraction analysis (XRD). Brunauer–Emmett–Teller (BET) explains the physical adsorption of gas molecules on the solid surface and uses measurement of the specific surface area of materials. Due to its vast surface area, biochar has been efficiently employed for the adsorption of heavy metal ions. The significant results of metal ions adsorption capacity revealed that biomass-driven biochar could be a better alternative for the removal and recovery of heavy metal ions from wastewater.
