Abstract

Residues of clopyralide in strawberries treated with herbicide preparation Lontrel 300 were determined using gas chromatographic method. The decrease of clopyralide content during the processing of contaminated fruits was observed. The rate of decomposition of this compound in model solutions (held at 75 degrees C, pH 3.6) followed first-order kinetics. 2,5-dicloropyridine was proved to originate under these conditions from parent compound.

摘要

使用气相色谱法测定了用除草剂制剂龙灯300处理过的草莓中氯吡脲的残留量。观察到受污染果实加工过程中氯吡脲含量的降低。该化合物在模型溶液（75摄氏度，pH 3.6）中的分解速率符合一级动力学。事实证明，在这些条件下，2,5-二氯吡啶由母体化合物产生。
