The solvent extraction of gold, palladium, technetium, indium and rhenium from both mixtures of a deep eutectic solvent with aqueous salt solutions and of two different aqueous salt solutions has been performed. Initially using gold and then the other metals the solvent extraction results were interpreted using an activity coefficient/function equation (specific ion interaction theory). The most important presented result is the addition of a new term to the specific ion interaction theory equation. Using the new model it will be possible to make predictions of the behaviour of a solvent extraction system where one of the liquid phases is a mixture of aqueous salts and the deep eutectic solvent.
从深共晶溶剂与盐水溶液混合物和两种不同盐水溶液混合物中萃取金、钯、锝、铟和铼的溶剂萃取已经完成。最初使用金，然后使用其他金属，使用活度系数/函数方程（特殊离子相互作用理论）解释溶剂萃取结果。最重要的结果是在特殊离子相互作用理论方程中添加了一个新项。使用新模型，将有可能对溶剂萃取系统的行为进行预测，其中一个液相是盐水和深共晶溶剂的混合物。
