3种吸附剂对二氯喹啉酸和莠去津吸附效果的研究

    Adsorption effects of three adsorbents on quinclorac and atrazine

    • 摘要:
      目的  寻找合适的二氯喹啉酸和莠去津吸附剂,减轻其残留对农作物产生的药害。
      方法  用甲醇淋洗添加了二氯喹啉酸或者莠去津的吸附剂(土壤和吸附剂混合物),淋洗液浓缩后经高效液相色谱检测分析。
      结果  吸附剂单独使用时,不同粒径的活性炭(F280、F380、F580)对二氯喹啉酸和莠去津吸附率均达到80%以上,表现出良好的吸附性。吸附剂与土壤混合处理后,F580活性炭对二氯喹啉酸和莠去津吸附率分别为73.85%和59.49%,效果良好。
      结论  活性炭F580可以有效地吸附水和土壤中的二氯喹啉酸和莠去津,具有实际应用和推广价值。

       

      Abstract:
      Objective  To discover suitable adsorbents of quinclorac and atrazine and to reduce injury to crops caused by their residues.
      Method  The methanol elutions of the adsorbents ( mixtures of soil and different adsorbents) containing quinclorac or atrazine were concentrated, and then analyzed by high-performance liquid chromatography.
      Result  When each adsorbent was used alone, the adsorption rates of active charcoals with different particle sizes (F280, F380, F580) to quinclorac and atrazine were all above 80% indicating excellent adsorption effects. When the adsorbents were mixed with soil, the adsorption rates of F580 active charcoal to quinclorac and atrazine were 73.85% and 59.49%, respectively, indicating relatively good adsorption effects.
      Conclusion  F580 active charcoal can absorb the residues of quinclorac and atrazine in water and soil, and it has great value for application and popularization.
