| Abstract: | 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.; |
