WASTEWATER TREATMENT PROCESS |
| abstract |
Acid effluent liquid is treated by contacting with a soln. in water insoluble organic solvent of an amine of formula (I) (where R1 and R2 are H, halogen or 1-4C alkyl, R is 8-10c alkyl or alkenyl) to transfer water soluble anions to the organic phase sepg. the water phase; contacting the organic phase with aq. alkali (II) to transfer impurities to the aq. alkaline phase and recovering the amine n organic solvent. Method removes aromatic org. sulphonates, nitro cpds. and phenols from e.g. dye prodn. processes. The use of (I) allows high degree of sepn. and high solubility in organic solvent. |
