With the vigorous development of the leather industry, the environmental pollution problem originating from tannery wastewater is becoming increasingly serious, which can be solved by using advanced adsorption technology. As a biodegradable natural biomaterial, starch has a wide range of sources and has gradually become one of the best choices for preparing superabsorbent polymers. The excellent characteristics of starch-based superabsorbent polymer make it widely applied in wastewater treatment. Therefore, this paper reviews the research progress of starch-based superabsorbent polymer in recent years by removing metal ions and typical organic compounds from tannery wastewater. Firstly, the synthesis methods and characteristics of starch-based superabsorbent polymers are discussed. Secondly, the main factors influencing the adsorption performance of starch-based superabsorbent polymer have been introduced. Thirdly, the present situation of treating tannery wastewater with starch-based superabsorbent polymer is summarized. Finally, some problems existing in the practical application of starch-based superabsorbent polymer are proposed. Although starch-based superabsorbent polymer shows excellent adsorption properties, there remain several issues such as recycling that needed to be addressed. This review is of benefit for the high-value utilization of starch-based superabsorbent polymers in reducing environmental pollution caused by tannery wastewater.

淀粉基高吸水性聚合物的设计及其去除制革废水中典型污染物的最新进展

随着制革工业的蓬勃发展，制革废水带来的环境污染问题日益严重，采用先进的吸附技术可以解决这一问题。淀粉作为一种可生物降解的天然生物材料，来源广泛，已逐渐成为制备高吸水性聚合物的最佳选择之一。淀粉基高吸水性聚合物的优异特性使其在废水处理中得到广泛应用。因此，本文综述了近年来淀粉基高吸水性聚合物去除制革废水中金属离子和典型有机化合物的研究进展。首先，讨论了淀粉基高吸水性聚合物的合成方法和特性。其次介绍了影响淀粉基高吸水性聚合物吸附性能的主要因素。再次，总结了淀粉基高吸水性聚合物处理制革废水的现状。最后提出了淀粉基高吸水性聚合物实际应用中存在的一些问题。尽管淀粉基高吸水性聚合物表现出优异的吸附性能，但仍存在一些需要解决的问题，例如回收利用。该综述对于淀粉基高吸水性聚合物在减少制革废水造成的环境污染方面的高价值利用是有益的。
