应用于土遗址文物脱盐的高分子材料

Research progress of salt-resistant superabsorbent polymer for desalination to earthen ruins

运用吸附脱盐法除去土遗址中的可溶盐,所用的吸附材料是脱盐的关键要素之一。本文介绍了用于土遗址脱盐的吸附材料发展历程及其现状,重点介绍了耐盐性高分子吸水材料用于土遗址基体中盐类脱除的机理、存在的问题及发展方向,文中还对高分子吸水材料可能取得的进展和前景进行了展望。

It is important to choose suitable superabsorbent to remove the soluble salt in earthen ruins by adsorption. The present sit-uation and developing process of the superabsorbent materials were discussed in this article and it is the highlights when it was ap-plied in earthen ruins to desalination. The mechanisms of the desalination were introduced. The existing problems and prospects on application of superabsorbent to desalination in earthen ruins was mentioned.
