摘　　要：设计了不同防老剂配方量的丁苯橡胶凝聚水,采用高效液相色谱法(HPLC)测定了环保型丁苯橡胶(SBR)1500E凝聚水中的防老剂烷基-芳基-对苯二胺复配物(EPPD)含量。配制不同质量浓度(ρ)的防老剂EPPD水溶液并检测其化学需氧量(COD),进而确定了的ρ-COD标准曲线,根据HPLC检测结果和ρ-COD标准曲线可得出凝聚水样品中防老剂对水体COD的贡献率。The different formulas of antioxidant EPPD in coagulation water of styrene-butadiene rubber（1500E） were designed,then the content of which was determined by using high performance liquid chromatography（HPLC）.The COD of configuration EPPD solution of different concentration was determined for making ρ-COD standard curve.According to the result of HPLC and ρ-COD curve,the contribution rate of COD in water samples can be found.
