提碘技术研究进展

Progress of Extracting Iodine Technology

碘作为重要的化工原料,在国民经济中有重要作用,在世界范围内属于紧缺资源。碘资源广泛存在于海洋水体,岩石矿藏和油气田卤水中,且储量巨大。本文简单介绍了碘的主要应用和工业生产现状,重点论述了目前世界上提取碘的主要工艺方法,如空气吹出法,离子交换法和活性炭吸附法等,对不同工艺的生产特点进行了探讨。着重介绍了我国碘资源的分布情况,综述了国内的提碘技术进展,并展望了今后提碘技术的发展方向。

As an important chemical raw materials, iodine plays a vital role in national economy, and is a scarce resources in the world at present. Iodine resources exist widely in ocean, minerals and oil or gas field brine, and have an enormous reserves. The application of iodine and the present status of its industrial production were briefly introduced. The main methods of extracting iodine in the world were introduced emphatically, for example, blow-out, ion exchange, activated carbon adsorption methods and so on. The characteristic of different methods were also investigated. The distribution of China＇s iodine resources and technology for extracting iodine were discussed in this paper. At last, the future development direction of iodine extraction in China was prospected.
