摘要
海藻酸钠是一种天然多糖,因其成凝胶条件及工艺简单,并具有生物安全性和生物相容性等特点,受到广泛关注。通过和其他物质复合,可进一步改善和丰富海藻酸钠凝胶的性能,拓宽其在水处理中应用前景。本文主要综述了海藻酸盐复合凝胶发展现状及其结构特点、理化性质和吸附特性,总结和归纳了海藻酸盐复合凝胶的分类和制备方法等,并深入对比和分析了海藻酸盐复合凝胶作为吸附剂在水处理中的研究进展和存在的问题,并对其后续研究和应用进行展望。
Sodium alginate(SA)which is a natural polysaccharide has attracted wide attention not only due to the simple gelatinization conditions and easy operation process,but also its good biodegradability and excellent biocompatibility.Apart from that,compositing with other chemical substances improves the properties of SA gels.They will show a promising application prospect in water treatment area in the future.The article reviews the research advance of the structure characteristics,the physical-chemical and adsorption properties of SA composite gels.Besides,the classifications and preparation methods of SA composite gels are summarized and concluded systematically.In addition,we further analyze and compare the research problems and progress of SA composite gels used as adsorbents in water treatment.At last,we point out the further research direction and applications of SA composite gels in order to provide some suggestion to solve water pollution problems.
