    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.
