摘要
锆铪分离技术大体分为火法分离和湿法分离 .着重介绍了湿法分离的溶剂萃取法中甲基异丁酮 -硫氰酸法、三辛胺法、磷酸三丁酯法和改进的 N2 35 - H2 SO4法 .锆铪主要在核能工业上应用 .锆铪工业的发展与核能工业紧密关联 .加强锆与铪分离工艺的研究 。
The technology for the separation of Zr and Hf is generally classified into pyrome\| tallurgical technology and hydrometallurgical technology. In this paper, MIBK\|HCNS process, TOA process, TBP\|HCl\|HNO\-3 process and improved N235\|H\-2SO\-4 process were underlined, which are included in solvent extraction, a hydrometallurgical technology. Zr and Hf are mainly used in the nuclear industry, thus the development of Zr and Hf industry is closely linked to the nuclear industry. Strengthening the research on the technology for the separation of Zr and Hf is of important strategic significance for the development of the production of Zr and Hf materials and enhancement of the nuclear power and national defence industries in China.
