在硫酸溶液中分离锆、铪由于其固有的优点,受到国内外研究者的普遍重视,并相应地提出了液-液萃取分离的流程。然而,分离的规律不易掌握,且在试验和生产中常出现一些令人难以捉摸的产品不合格现象。我们以现有的数据和经验为依据,从锆铪在硫酸溶液中的状态出发,探讨出现的问题和现象,分析其状态变化对液-液萃取分离的影响。 Due to its inherent advantages, zirconium and hafnium have been widely studied by researchers at home and abroad, and the corresponding scheme of liquid-liquid extraction and separation has been put forward. However, the laws of separation are not easy to grasp and there are often some elusive product failures in testing and production. Based on the existing data and experience, we discuss the problems and phenomena that occur from the state of zirconium and hafnium in sulfuric acid solution, and analyze the influence of state changes on the separation of liquid-liquid extraction.
