摘　　要：用络合萃取法对6-硝生产母液中的6-硝基-1,2-重氮氧萘-4-磺酸进行了萃取研究。在室温下,以体积分数30%的三辛胺(N-235)氯仿溶液为萃取剂,萃取剂与母液体积比1∶1,萃取60min,萃取可率达96.1%;以质量分数12%的NaOH溶液为反萃取剂反萃有机相,有机相与NaOH溶液体积比2∶1,反萃取60min,反萃取率可达94.3%。A complexometric extraction method of extracting 6-nitro-1 and 2-azoxynaphthalene-4-sulfonic acid in its mother solution is studied. At the room temperature, taking 30% （v） trioctylamine（N-235） chloroform solution as an extractant, when the extractant and mother solution volume ratio is 1.1 and extracting 60 minutes, the extraction yield can reach 96.1%. Using 12%（m） NaOH solution as a strip agent, when the organic phase and strip agent volume ratio is 2.1 and stripping 60 minutes, the strip yield can reach 94.3 %.
