Industrial wastewater often contains heavy metals that, if not removed, pose a risk to the environment. Therefore, an extended overview of different methods for heavy metal removal by columns was conducted. Column studies are dependent on the flow rate, bed height and diameter, breakthrough curve, type of wastewater, and adsorbent. The fixed‐bed column is most commonly used for metal sequestration in aqueous media. Column studies have advantages due to industrial scale applicability and can treat large quantities of wastewater. Many kinetics models are applied in column studies like Adam‐Bohart, Yoon Nelson, Bed Depth/Service Time, Thomas, and Clark. This paper deals with the use of modified or non‐modified adsorbents for the treatment of metal‐laden water and wastewater by column technique.

固定床色谱柱去除重金属的评论

工业废水通常包含重金属，如果不去除，将对环境构成威胁。因此，对通过色谱柱去除重金属的不同方法进行了广泛的概述。色谱柱研究取决于流速，床高和直径，穿透曲线，废水类型和吸附剂。固定床色谱柱最常用于水性介质中的金属螯合。由于工业规模的适用性，色谱柱研究具有优势，并且可以处理大量废水。许多动力学模型被应用在色谱柱研究中，例如Adam-Bohart，Yoon Nelson，床深度/服务时间，Thomas和Clark。本文涉及使用改性或非改性吸附剂通过柱技术处理载有金属的水和废水的方法。
