离子交换树脂脱除淡化海水中微量硼的研究进展

Advances in Removal of Trace Boron by Ion Exchange Resin from Desalination Seawater

饮用含硼的水会对人体和动植物产生相当大的危害,因此海水淡化后的硼含量应越小越好,而离子交换是最适合脱除海水淡化后剩余微量硼的技术。文章总结了水中硼的存在形式,分析了离子交换适用于去除微量硼的原因及其脱硼原理,对比了几种吸附剂的脱硼效果及影响离子交换树脂脱硼的因素等,并对离子交换树脂的经济优势做了说明。

Boron in drinking water can cause great adverse effects on human,animals and plants,therefore,the boron in water after desalination should be as low as possible.The method of ion exchange is suitable for the removal of trace boron from desalination seawater.In this paper,the morphology of boron in water was summarized,the reason and principle of boron removal by ion exchange was analyzed,then the boron adsorption capacities of the various adsorbents were compared,the parameters of influence and economic advantages for boron-specific resin were introduced at last.
