摘要：
A method for removing impurities from an aqueous mixture or purified aqueous by extracting the aqueous mixture or purified aqueous mixture with an extraction solvent in an extraction zone to form an extract stream and the raffinate stream; and optionally separating the extract stream and a solvent rich stream in a separation zone to form a high boiling point organic impurities stream and a recovered extraction solvent stream.
