In this study, hemicellulose was mostly removed from biomass (larch and oak) using a sulfuric acid pretreatment. Biochar was then prepared from raw and pretreated biomass using a carbonization process. Biochar derived from pretreated biomass had an aromatic and graphitized structure, and functional groups were observed on the surface. The specific surface area was higher for biochar obtained from pretreated biomass than biochar derived from raw biomass. The biochar obtained from pretreated biomass contained a greater number of micropores than biochar derived from raw biomass. The diazinon removal rate was the highest for biochar that was obtained from pretreated biomass when 10% of the biochar was added to the soil. As a result of the adsorption of diazinon onto the biochar obtained from pretreated biomass, the R2 value of the Langmuir isotherm was higher than that of the Freundlich's R2.
