Abstract: The extraction properties and regularity of rare earths by open chain crown ether 1, 11-di (8-quinoline) -3, 6, 9-trioxaoundecane (noted as L) were investigated. And the effects of aqueous acidity, terminal group and organic acid group anion on the extractability of rare earths were examined respectively.
