Analysis of char prepared by pyrolysis of dabai (Canarium odontophyllum) nutshells as a potential precursor of biocarbon used for wastewater treatment

Dabai (Canarium odontophyllum) nutshells have considerable potential to be used as a viable precursor for biomass-based activated carbon. The material was carbonized at temperature of 700 °C 2 h, heating rate 10 °C/min under nitrogen gas flow. char analyzed the following ways: percentage yield, ash content, Fourier transform infrared spectroscopy, scanning electron microscopy with energy dispersive x-ray analysis, and Brunauer, Emmett, Teller surface area. had maximum area 428 m2/g adsorption-desorption isotherm that similar Type I adsorption isotherm, based on IUPAC classifications. also high carbon content (up 93.6%) low (3.67%). Therefore, dabai were found suitable lignocellulosic synthesis
