Example Embodiment
[0031] Example 1
[0032] Biochar, activated carbon, and clay minerals were added to 300 g of 1,2,4-trichlorobenzene in an amount of 1% of the dry weight of the soil, and the concentration of 1,2,4-trichlorobenzene was 7 μg g ?1 In the contaminated soil of 28%, stir and mix well, then transfer to a 1-L wide-mouth bottle, adjust the soil moisture content to 28%, and compact the soil to a density of 1.3 g cm ?3 , sealed with a rubber stopper with air inlet and outlet, and incubated at 25 °C in the dark. The treatment without any material was used as a control. At the 1st, 2nd, 4th, 8th, 12th and 24th weeks of cultivation, aeration was carried out with a closed trapping device. After the ventilation was over, the soil was collected, and the total amount of chlorobenzene was analyzed by n-hexane-accelerated solvent extraction, and the total amount of chlorobenzene was analyzed by extraction with butanol. Bioavailability of chlorobenzene in soil.

[0035] Example 2
[0036] Biochar was added to 300 g of pentachlorobenzene at a concentration of 0.1% of the dry weight of the soil to a concentration of 1 μg g ?1 In the contaminated soil of 28%, stir and mix well, then transfer to a 1-L wide-mouth bottle, adjust the soil moisture content to 28%, and compact the soil to a density of 1.3 g cm ?3 , sealed with a rubber stopper with air inlet and outlet, and incubated at 25 °C in the dark. The treatments with 0.5% wt, 1% wt and 2% wt of biomass char added were the same as above, and the treatment without biomass char was used as the control (0% wt). At the 1st, 2nd, 4th, 8th, 12th and 24th weeks of cultivation, aeration was carried out with a closed trapping device. After the ventilation was over, the soil was collected, and the total amount of chlorobenzene was analyzed by n-hexane-accelerated solvent extraction, and the total amount of chlorobenzene was analyzed by extraction with butanol.

[0039] Example 3
[0040] Biochar was added to 300 g at 0.1% of soil dry weight and the concentration of 1,2,4,5-tetrachlorobenzene was 0.9 μg g ?1 In the contaminated soil of 28%, stir and mix well, then transfer to a 1-L wide-mouth bottle, adjust the soil moisture content to 28%, and compact the soil to a density of 1.3 g cm ?3 , sealed with a rubber stopper with air inlet and outlet, and incubated at 25 °C in the dark. The treatments with 0.5% wt, 1% wt and 2% wt of biomass char added were the same as above, and the treatment without biomass char was used as the control (0% wt).
