新型废氨吸附材料研究进展

Research progress of new waste ammonia adsorption materials

氨气作为农业生产过程中排放和泄漏最多的有害气体之一,过量的氨气会导致生态系统恶化,对人类的健康构成重大损伤。吸附法是处理氨气最常见的有效方法之一,目前氨气吸附材料和材料改性方法发展不明确,虽然前人对氨气吸附材料有所总结,但新型氨气吸附材料近年来发展迅速需要补充。综述了近年来相关材料对氨气吸附的研究现状,补充论述碳纳米管、石墨、离子液体和低共熔溶剂等新型材料研究进展,总结氨气吸附材料吸附机理、发展方向和改性策略,对氨气吸附材料的发展提出建议。

Ammonia,as one of the most harmful gases emitted and leaked during agricultural production,in excess can lead to ecosystem deterioration and pose significant damage to human health.Adsorption is one of the most common and effective methods for treating ammonia.At present,the development of ammonia adsorption materials and material modification methods is not clear.Although the previous researchers have summarized the ammonia adsorption materials,the new ammonia adsorption materials have been developed rapidly in recent years and need to be supplemented.In this paper,we reviewed the current research status of ammonia adsorption by related materials in recent years,supplemented the research progress of new materials such as carbon nanotubes,graphite,ionic liquids and low eutectic solvents,summarized the adsorption mechanism,development direction and modification strategy of ammonia adsorption materials,and put forward suggestions for the development of ammonia adsorption materials.
