Zeolites possess a microporous crystalline structure, a large surface area, and a uniform pore size. Natural or synthetic zeolites are commonly utilized for adsorbing organic and inorganic compounds from wastewater because of their unique physicochemical properties and cost-effectiveness. The present review work comprehensively revealed the application of zeolites in removing a diverse range of wastewater contaminates, such as dyes, heavy metal ions, and phenolic compounds, within the framework of contemporary research. The present review work offers a summary of the existing literature about the chemical composition of zeolites and their synthesis by different methods. Subsequently, the article provides a wide range of factors to examine the adsorption mechanisms of both inorganic and organic pollutants using natural zeolites and modified zeolites. This review explores the different mechanisms through which zeolites effectively eliminate pollutants from aquatic matrices. Additionally, this review explores that the Langmuir and pseudo-second-order models are the predominant models used in investigating isothermal and kinetic adsorption and also evaluates the research gap on zeolite through scientometric analysis. The prospective efficacy of zeolite materials in future wastewater treatment may be assessed by a comparative analysis of their capacity to adsorb toxic inorganic and organic contaminates from wastewater, with other adsorbents.
沸石具有微孔晶体结构、大表面积和均匀的孔径。由于其独特的物理化学性质和成本效益,天然沸石或合成沸石通常用于从废水中吸附有机和无机化合物。本综述工作全面揭示了沸石在去除各种废水污染物方面的应用,如染料、重金属离子和酚类化合物,这是在当代研究框架内进行的。本综述工作总结了关于沸石的化学成分及其通过不同方法合成的现有文献。随后,本文提供了广泛的因素来研究天然沸石和改性沸石对无机和有机污染物的吸附机制。本综述探讨了沸石从水基质中有效去除污染物的不同机制。此外,本综述还探讨了 Langmuir 和伪二阶模型是用于研究等温吸附和动力学吸附的主要模型,并通过科学计量分析评估了沸石研究的差距。通过比较沸石材料从废水中吸附有毒无机和有机污染物的能力与其他吸附剂,可评估沸石材料在未来废水处理中的预期效果。
