EXTRACTION METHOD OF CLEANING WASTE WATER FROM AROMATIC AMINES Russian patent published in 2011 - IPC C02F1/26 B01D11/04 G01N33/18 C02F101/38 C02F103/36

Abstract RU 2431606 C2

FIELD: chemistry.

SUBSTANCE: in order to realise the method, aromatic amines are extracted from waste water with an emulsion of aqueous solution of an inorganic acid with ionisation constant higher than 10 in an organic solvent.

EFFECT: high degree of extraction of aromatic amines from waste water with minimum consumption of reagents and combining extraction and re-extraction processes at one step.
