摘　　要：分别建立歧化松香酸钾、饱和脂肪酸钾、高分子凝聚剂、三烷基氯化铵、防老剂EPPD、防老剂SP/TNP 6种常见助剂的浓度对化学需氧量(COD)标准曲线,通过计算得到各组分在乳聚丁苯橡胶装置凝聚水中的残留量对COD的贡献率,实测数据表明残留防老剂EPPD所贡献的COD值为1.72,防老剂SP/TNP所贡献的COD值为2.12。C-COD standard curve was established include rosin acid potassium, saturated fatty acid potassium, high polymer coagulant concentration, tri-alkyl ammonium chloride, antioxidant EPPD, an- tioxidant SP/TNP etc. Contribution rate to COD by the additive residues in condensation water of e- mulsion polymerized styrene butadiene rubber unit the residue of antioxidant EPPD contribution to the idant SP/TNP was 2.12. was calculated. The measured data suggested that COD was 1.72 ,the contribution to COD of antiox-
