摘要:

为了解决阿特拉津给土壤带来的污染问题以及寻找吸附效果较好的活性炭基质,本研究利用高效液相色谱(HPLC)技术检测了阿特拉津溶液和悬浮液经煤、木、果和竹质4种生物炭处理后的残留量,并对其在阿特拉津溶液和土壤中的吸附动态进行检测。结果表明,煤质活性炭对初始浓度为100 mg/L和10 mg/L的阿特拉津溶液和悬浮液的吸附效果较好,其吸附率为5.651%~68.42%;当阿特拉津初始浓度为100 mg/L时,煤质活性炭在40 min时对阿特拉津溶液的吸附率高达23.49%;与对照组相比,当阿特拉津的初始浓度为100 mg/L时,土壤中阿特拉津经煤质活性炭处理42天后的残留浓度最低,活性炭吸附率达到91.39%。综上,煤质活性炭能有效降解溶液及土壤中阿特拉津含量,这将为阿特拉津污染土壤的改良研究奠定基础。

Abstract:

To solve the problem of soil pollution caused by atrazine and look for the active carbon matrix with better adsorption effect, high performance liquid chromatography (HPLC) was used to detect the residue of atrazine solution and suspension after treatment with four kinds of biochar, such as coal, wood, fruit and bamboo, in order to detect its adsorption dynamics in atrazine solution and soil. The results showed that, the coal-based activated carbon had better adsorption effect on atrazine solution and suspension with initial concentration of 100 mg/L and 10 mg/L, and the adsorption rate was 5.651%-68.42%; when the initial concentration of atrazine was 100 mg/L, the adsorption rate of coal-based activated carbon for atrazine solution was up to 23.49% at 40 min; compared with the control group, when the initial concentration of atrazine was 100 mg/L, the residue concentration of atrazine in the soil treated with coal-based activated carbon was the lowest after 42 days, and the adsorption rate of activated carbon was 91.39%. In conclusion, coal-based activated carbon can effectively degrade the content of atrazine in solution and soil, which will lay a foundation for the improvement of atrazine contaminated soil.
