In a conical flask, biochar was prepared by pyrolysised reaction method,with peanut shell as material and temperature at 300 ℃ for 4 h. The obtained biochar was further functionalized with sodium sulfide. The results indicated that the same biochar had different adsorption properties under different time and temperature conditions. The functionalized biochar with different functional groups showed different adsorption capacity to organic pollutant. Among them, the functionalized biochar contains S-hetero-atomic functional groups showed the strongest adsorption effect. The method improved the preparation of biochar, reduced the cost, simplified the process, and enhanced the adsorption capacity.
