Abstract:

As a natural high molecular compound, starch has advantages, such as abundant sources, low in price, biodegradable, etc. Modified starch has widely been used for removing heavy metallic ions from wastewater. In order to improve its adsorption capacity, some modified starch with new types of structures is designed and synthesized, among which dialdehyde modified starch is different from traditional ones in structure and characteristics. Based on the introduction of its synthetic method, the types, structures and characteristics of dialdehyde modified starch for removing heavy metallic ions from wastewater are summarized, providing reference for the design of more new modified starch in future.

Key words: dialdehyde modified starch, Schiff base, heavy metal ions, wastewater treatment

摘要:

淀粉作为天然高分子化合物具有来源广泛、价格低廉和可生物降解等优点,改性淀粉被广泛应用于废水中重金属的处理。为了改善其吸附性能,设计并合成了一些新型结构的改性淀粉,其中双醛改性淀粉在结构和特点上与传统的改性淀粉不同。在介绍其合成方法基础上,总结了双醛改性淀粉的种类、结构以及处理废水中重金属的特点,为今后设计更多的新型改性淀粉提供参考。
