含硼溶液硼分离技术进展

The Progress of Boron Separation from Boron Containing Solution

虽然硼在工业领域有着广泛应用,但我国的硼资源对外依存度高。同时,随着工业的发展,水体中硼含量过高的问题日趋严重。从含硼溶液中分离硼,不仅可以降低环境污染,还可以有效回收硼资源,降低我国硼资源的对外依存度。因此,对含硼溶液硼分离技术的现状及进展进行了介绍,包括吸附法、膜分离法、沉淀法和萃取法等,分析了各方法的优缺点,为溶液中硼的综合利用提供思路。

Boron are widely used in industry and the boron resources of China are highly dependent on foreign countries.Meanwhile,with the development of industry,the problem of excessive boron content in water is becoming more and more serious.Separation of boron from boron containing solution can not only reduce environmental pollution,but also effectively recover boron resources and reduce the external dependence of boron resources in China.Therefore,this paper introduces the present situation and progress of boron separation technology from boron containing solution,includes adsorption method,membrane separation method,precipitation method and extraction method.The advantages and disadvantages of each method are analyzed which provides ideas for the comprehensive utilization of boron in solution.
