摘 要:
建立了气相色谱-质谱法测定磺酰脲类除草剂豆磺隆在土壤中的残留量方法,利用豆磺隆的热不稳定性,对其水解产物4-氯-6-甲氧基嘧啶胺进行选择离子测定,定性、定量准确,排除了大豆中复杂基质的干扰,方法的线性、回收率、精密度和检出限均符合残留分析的要求。[著者文摘]

Abstract:
A method for the determination of sulfonylurea herbicides chlorimuron-ethyl by GC-MS was proposed. The extracted ions 4-chloro-6-methoxy-2-pyrimidinamine from hydrolysis of chlorimuron-ethyl based on heat instability were determined. The method is accurate and eliminates the interference of complex matrix. The linear range, recovery, precision and detection limit satisfy the demand of residue analysis.[著者文摘]
