| 摘要 |
A method for the removal of liquid or solid impurities from an impurities-containing liquid mixture wherein the impurities immiscible or occasionally miscible with the liquid medium are emulsified or finely suspended in the liquid medium, which comprises kneading the impurities-containing liquid mixture with a viscoelastic material having an affinity with said impurities and having substantially no affinity with said liquid medium, and thereby having the viscoelastic material take up the impurities and separating out the purified liquid medium. According to this method, various liquid wastes can be purified, and noble resources can be recovered from the wastes and re-used, and the separated liquid medium, particularly aqueous medium which is not useful can be thrown away without encountering problems of environmental pollution.
