摘　　要：[目的]测定氟吗啉Z、E异构体在不同pH值(3.0～9.0)水中平衡溶解度。[方法]采用反相高效液相色谱法测定了氟吗啉Z、E异构体水中的质量浓度。[结果]20℃氟吗啉Z异构体在pH值3.0水中的溶解度为95 mg/L,在pH值5.0～9.0水中的溶解度为59～68 mg/L;氟吗啉E异构体在pH值3.0～9.0水中的溶解度为114～121 mg/L。[结论]氟吗啉Z异构体在酸性水中的溶解度较大,氟吗啉E异构体水溶解度受pH值影响不大。[Aims] The equilibrium solubility of flumorph （Z/E isomer） in water of different pH was detected. [Methods] A RP-HPLC method was established and used to detect the concentration of flumorph （Z/E isomer） in water. [Results] The equilibrium solubility of flumorph Z-isomer in water of pH as 3.0 was 95 mg/L at 20 ℃, and 59-68 mg/L in water ofpH from 5.0 to 9.0. The equilibrium solubility of flumorph E-isomer in water of pH from 3.0 to 9.0 was 114-121 mg/L at 20 ℃. [Conclusions] The equilibrium solubility of flumorph Z-isomer was higher in acidic water, and that of flumorph E-isomer was not affected intensely by pH of water.
