摘要: 镍在新能源汽车电池领域、电镀等行业有广泛的应用，随着国家双碳战略的进一步推进，这些行业产生的含镍(Ni²⁺)废水的处理对于环境保护而言越来越重要。传统的Ni²⁺废水主要通过离子交换树脂、化学沉淀法、流化床结晶造粒等技术脱除其中的Ni²⁺，但这些处理过程存在选择性差以及产生二次污染等问题。本实验利用钴基咪唑酯骨架材料(Zeolite Imidazolate Framework，ZIF-67)可与Ni²⁺反应形成镍钴水滑石的特点，设计了ZIF-67应用于Ni²⁺去除研究的综合化学实验。在本实验中，ZIF-67与Ni²⁺通过化学反应结合在一起，能有效提高对Ni²⁺的选择性。本实验不仅包含材料制备、表征、吸附性能等实验内容，还包含模型分析和机理研究，通过对吸附机理进行深入研究，有利于培养学生的科研兴趣、创新思维和实践能力。本实验课堂时间约为8 h，时长适用于本科生综合化学实验教学。通过本实验，学生既能熟悉吸附法去除废水中Ni²⁺的基本原理和分析过程，又能夯实专业基础知识，明确理论可以指导工业应用，从而培养学生综合能力，提升学生的科学素养和创新精神。

Abstract: Nickel, prevalently utilized in sectors such as new energy vehicle batteries and electroplating, has brought the environmental challenges, especially in the context of the national dual carbon strategy. The treatment of nickel (Ni²⁺)-enriched wastewater generated by these industries is pivotal for environmental conservation. Traditional Ni²⁺-enriched wastewater treatments, including, ion exchange resins, chemical precipitation, and fluidized bed crystallization granulation technology, often suffer from poor selectivity and the risk of secondary pollution. This study introduces an innovative approach employing a cobalt-based imidazole framework material, ZIF-67, which interacts with Ni²⁺ to form the nickel-cobalt layered double hydroxides (NiCo-LDH), effectively enhancing Ni²⁺ removal. The experiment spans material preparation, characterization, and adsorption performance assessment, supplemented by model analysis and mechanistic investigation. This multifaced approach aims not only to elucidate the adsorption mechanism but also to cultivate students’ research interest, innovative thinking, and practical skills. Tailored for an 8-hour undergraduate comprehensive chemistry laboratory session, this experiment enables students to grasp fundamental principles and analytical methods for Ni²⁺ removal from wastewater. It also solidifies their foundational knowledge, demonstrating the practical application of theoretical concepts in industrial settings. This experiment is designed to bolster students' comprehensive abilities, enhance their scientific literacy, and foster their innovative spirits.
