摘　　要：用 PCW-7-甲苯络合萃取剂处理富马酸废水 ,萃取液用碱液反萃回收 ,每立方米废水可回收 9kg富马酸 ,其含量大于97%。研究了影响萃取效果的相关因素 ,确定了适宜的工艺条件。Wastewater from the production of Fumaric acid was treated by one-stage extraction process using PCW-7 extractant. The extract is treated by back-extraction with alkali liquor. About 9 kg Fumaric acid can be recovered from 1 m+3 of wastewater. The mass concentration of Fumaric acid is greater than 97%.The certain factors which influence the extracting efficiency were also discussed.;
