中文摘要：

系统地介绍了碘的提取回收方法及研究进展,分析了目前应用中存在的主要问题。在传统提碘方法不适宜低品位含碘资源的情况下,结合国内外研究进展,提出以离子交换树脂和活性炭为代表的吸附剂、浮选和液膜技术等将是未来低品位碘提取回收研究和发展趋势。

英文摘要：

Extraction and recovery methods of iodine and their research progress are briefly introduced. The existing problems in the applications are analyzed. Under the conditions that the traditional methods are not suitable for the low grade resources,the adsorbent,flotation and liquid membrane technologies based on ion exchange resins and activated carbon adsorbents are proposed as the trends of recovering low grade iodine containing resources in the future.
