摘要
研究了在酸性介质中D 990离子交换树脂吸附铂和铼的性能。在较低酸度下 ,该树脂对铂和铼有良好的吸附性能 ,吸附容量分别达到铂 10 2mg/g干树脂和铼 16 2mg/g干树脂。在较高酸度下 ,铼很容易解吸 ,而铂不解吸仍留在树脂上 ,此特性有利于铂和铼的分离。
The adsorptivity of D 990 ion exchange resin for platinum and rhenium in acid solution was investigated.Experimental results show that a good adsorptivity of this resin for platinum and rhenium under lower acidity conditions is obtained.The adsorptive capacities are 102 mg Pt/g dry resin and 162 mg Re/g dry resin,respectively. Rhenium is easily desorped from the resin under higher acidity conditions,but platinum remaines on the resin under the same conditions.Thus the separation of platinum and rhenium is feasible.
