溶剂萃取过程中,由于搅动,摩擦发热等作用,产生了许多小气泡。这些气泡将一定数量的水相以难以破裂的悬浮小球的形式,带入反萃,使得金属离子的分离不彻底。因此,促使气泡破裂,在萃取,反萃过程中,有着相当重要的作用。 (一)絮凝剂PAM的应用 为了“破泡”,笔者设想用有机硅消泡剂和高分子絮凝剂作萃取原液中 Solvent extraction process, due to stirring, friction heat and so on, resulting in many small bubbles. These bubbles bring a quantity of aqueous phase into the back-extraction in the form of hard-to-break suspended pellets, so that the separation of the metal ions is not complete. Therefore, to promote bubble rupture, in the extraction, stripping process, has a very important role. (A) Application of flocculant PAM In order to “break the bubble”, I envisage the use of silicone defoamers and polymer flocculants for extraction of liquid
