摘　　要：本研究建立一套鉴别二氯喹啉酸产品中二氯喹啉酸盐的实验室检测方案,并提出相应的监管建议。采用“外观鉴别法”“含量鉴别法”和“离子色谱法”对二氯喹啉酸产品中的二氯喹啉酸盐和反离子对进行鉴定,可以区分产品中是否含有二氯喹啉酸盐以及盐的种类。该套鉴别方案成熟、可靠,应用场景多样,结合具体监管措施,可用于规范二氯喹啉酸农药的生产。This study aimed to establish a set of laboratory identification scheme for quinclorac salt in quinclorac products,and put forward corresponding supervision suggestions."Appearance identification method""content identification method"and"ion chromatography method"were used to identify quinclorac salt and counter ion pair in quinclorac products.Through the tests,we could distinguish whether the product contains quinclorac salt and the type of salt.The identification scheme is mature,reliable and suitable for various application scenarios.Combined with specific regulatory measures,it can be used to regulate the production of quinclorac pesticides.
