均相离子交换膜的研制

Preparations of homogeneous ion exchange membranes

均相阴、阳膜及双极性膜在同位素分离、废水处理、高纯水制备、直接从矿石中提取金属、酸和碱的制备等领域获得了实际应用。介绍制备均相阴、阳离子交换膜的γ-射线辐射接枝法、含浸法、涂浆法,制备双极性膜的单片法。

Preparations of homogeneous cation and anion exchange membranes and hi-polar membrane are introduced. The methods of preparating homogeneous cation and anion exchange membranes in- clude irradiation grafting by γ-ray, soaking method, paste-coating method, etc. However single slice method is chiefly used in the preparation of bi-polar membrane. The above obtained membranes can be widely used in various fields such as isotope separation, treatment of waste water, high pure water preparation, directly extracting metals from their ores, and directly preparating acid and base from their salt solution.
