摘要
伴随着电镀电解及电池工业的发展,对含重金属离子工业废水的处理需求日益陡增。工业废水的常用处理方法有物理处理、化学处理等。应用磁性水凝胶作为吸附剂处理废水中的重金属离子,呈现吸附效率高、可以多次循环使用等优点,成为了目前的研究热点。大量研究聚焦于磁性水凝胶的制备方法及对重金属离子的处理效果,但关于磁性水凝胶处理重金属离子的成本、不同制备方法制得的磁性水凝胶的吸附效果等缺乏对比,从而对磁性水凝胶处理重金属离子的实际应用带来困难。通过文献研究法,梳理水凝胶吸附重金属的原理和过程,并对不同方法制备出的磁性水凝胶吸附能力、成本等进行比较,为磁性水凝胶处理重金属离子的应用提供方法参考。
As the electroplating,electrolysis,and battery sectors continue to develop,there has been a growing need for effective treatment of industrial wastewater that contains heavy metal ions.Various methods are typically used to address this issue,including physical and chemical treatments.Recently,magnetic hydrogels have gained attention as adsorbents for removing heavy metal ions from wastewater due to their high adsorption efficiency and ability to be recycled multiple times.A significant amount of research has focused on the preparation methods of magnetic hydrogels and their effectiveness in treating heavy metals.However,there is a lack of comparative studies regarding the costs associated with using magnetic hydrogels for heavy metal removal and the adsorption performance of magnetic hydrogels produced through different preparation techniques.This gap presents challenges for the practical use of magnetic hydrogels in this context.Therefore,this paper employed a literature review approach to outline the principles and mechanisms involved in heavy metal ion adsorption by hydrogels while comparing both the adsorption capacities and costs associated with various preparation methods of magnetic hydrogels.This analysis aims to provide valuable insights for utilizing magnetic hydrogels in treating wastewater contaminated with heavy metals.
