AB  - In this study, rice straw was used as the raw materials of biomass carbon to 
      prepare biochar at different temperatures (400 degrees C, 500 degrees C, 600 degrees C, 700 degrees C, and 
      800 degrees C). In addition, cetyl trimethyl ammonium bromide (CTAB) modified biochar was 
      used to treat 2,4-dichlorophenol (2,4-DCP) in water. The influences of adsorbent 
      dosage, solution pH, adsorption time, and initial solubility of the 2,4-DCP 
      solution on the adsorption properties were investigated. The physicochemical 
      properties of biochar were investigated using SEM, FT-IR, BET surface area, and 
      pore size analysis. The results showed that the pyrolysis temperature had a great 
      influence on the biochar structure. CTAB provided hydrophilic and hydrophobic 
      groups to the modified biochar, which had increased adsorption capacity comparing 
      to unmodified biochar. The pH also had a significant effect on the adsorption 
      performance of biochar, and the adsorption performance of biochar decreased 
      significantly under alkaline conditions. The maximum adsorption capacities of 
      modified biochar and unmodified biochar were 59.81 and 20.89 mg/g, respectively, 
      indicating that the adsorption capacity of modified biochar was significantly 
      higher than that of unmodified biochar. The adsorption process of 2,4-DCP by rice 
      straw biochar conformed to the Second-order kinetic model and the Freundlich 
      isotherm adsorption model.
