Abstract Soybean straw biochar was prepared at 700℃ and modified by four methods including acid, alkali, amino modification, and iron magnetization. The sorption performance and mechanism of four modified biochar for imazethapyr were compared, and the effect of pH, temperature, and biochar dosage on the sorption amounts were discussed. In addition, the performance of modified soybean straw biochar for the sorption and fixation capacity of imazethapyr in soil was investigated. Modified soybean straw biochar had better sorption performance in the acidic environment with a pH value of 2~4. Comparing with the other three modified biochars, iron-magnetized biochar exhibited a higher sorption efficiency on imazethapyr. And its sorption behavior was better fitted by the pseudo-first-order kinetics and Langmuir model. The fitted Langmuir model indicated that the maximum sorption capacity of iron-magnetized biochar on imazethapyr reached 338.785mg/g; The sorption capacity for imazethapyr in the soil with 1% iron-magnetized biochar was 2.37 times higher than that without iron-magnetized biochar.

Key words： modified biochar imazethapyr adsorption soil remediation
