摘　　要：研究了用络合萃取法回收H酸废母液中染料中间体的多种影响因素 ,得出了最佳工艺参数。实验结果表明 ,通过萃取工艺 ,H酸废母液中染料中间体回收率可达 90 %以上 ,萃余液中CODcr在 (10 0 0～ 30 0 0 )mg/L之间 ,此工艺可使废母液中的回收物浓缩 5～ 10倍 。The various influential factors have been examined in the research on the recovery of dye intermediates from waste H-acid mother liquor by complex extraction process. The best technical parameters have been obtained. The experiment results indicate that 90% of intermediates in the waste mother liquor can be recovered, CODcr in the raffinate can be dropped to 1?000～3?000 mg/L, and the concentration of the extracted intermediates in the waste mother liquor can be enriched by 5～10 times. The used extractant can be reused after regeneration.
