Abstract

The adoption of green chemistry and sustainable engineering approaches into various processes became a trending, proactive practice. On this front, mature and well-developed processes, such as adsorption, have been complemented with different nuances in green chemistry and neoteric solvents, such as Deep Eutectic Solvents (DESs). This review provides a detailed reading of the adsorption studies that incorporated DESs for the development of adsorption materials, referred here as DES-based Adsorbents (DES-ADS).

The first part of this review summarizes the different DES-ADS in the literature under specific themes, namely, (i) applications, (ii) adsorbent materials, and (iii) DES components. The majority of DES-ADS are investigated for application in water/wastewater treatment (55.1%), followed by applications in protein isolation (12.7%), food (12.7%), biomass (7.6%), medical (3.4%) and other application (8.5%). The adsorbents were prepared from different base materials, and two or more base materials are often used as hybrids. As for the DES constituents, hydrogen bond acceptors were mainly chosen as choline chloride or other quaternary ammonium salts, while hydrogen bond donors include ethylene glycol, glycerol, urea in addition to other organic acids, polymerizable monomers, and sugars.

The second part of the review traces the different methodologies used within DES-ADS field through homogenization of different terms in the literature and categorizing each methodology based on the role of the DES within the different DES-ADS development schemes. Accordingly, three main synthesis routes were identified, namely, (i) Mixing, (ii) Dispersion, and (iii) Solvothermal methods. The discussion includes a critique about certain generalizations, assumptions, and shortcomings with regard to the DES’s nature and intrinsic properties during the development of such DES-ADS. This includes using improper reaction environments and dismissing the basic thermal properties of DES during the synthesis/functionalization of DES-ADS. Lastly, an alternative bottom-up framework is proposed for developing functional and task-specific DES-ADS.

This work provides a detailed mapping of trends and trajectories in the field of DES-based adsorbents and a critical discussion on the different methodologies used within the field. The framework devised in the light of such meticulous reading is a methodical, bottom-up approach that considers the principles from both fields (Adsorption and DES). Ultimately, this framework allows researchers to take the necessary steps towards answering the research question(s) imposed by the need for DES-ADS development. The framework can be also extrapolated into other fields in order to develop various DES-based adsorbents, membranes or other functional materials.

将深共晶溶剂整合到吸附过程的路线图：一个关键的审查和设计蓝图

在各个过程中采用绿色化学和可持续工程方法成为一种趋势，积极的实践。在这方面，成熟和发达的过程，如吸附，已经与绿色化学和新溶剂，如深共晶溶剂（DESs）的不同细微差别相辅相成。本文详细介绍了利用聚醚砜开发吸附材料（DES-ADS）的研究进展。本综述的第一部分根据具体的主题，即(i)应用，（ii）吸附剂材料和（iii） DES组分，总结了文献中不同的DES- ads。大多数DES-ADS应用于水/废水处理（55.1%），其次是蛋白质分离（12.7%）、食品（12.7%）、生物质（7.6%）、医疗（3.4%）和其他应用（8.5%）。吸附剂是由不同的基材制备的，两种或两种以上的基材通常用作杂化材料。对于DES组分，氢键受体主要选择氯胆碱或其他季铵盐，氢键给体除了其他有机酸、可聚合单体和糖外，还包括乙二醇、甘油、尿素。审查的第二部分通过文献中不同术语的同质化，并根据DES在不同DES- ads发展计划中的作用对每种方法进行分类，追溯了DES- ads领域中使用的不同方法。因此，确定了三种主要的合成路线，即(i)混合法，（ii）分散法和（iii）溶剂热法。讨论包括对DES的性质和内在特性在DES- ads开发过程中的某些概括、假设和缺点的批评。这包括在DES- ads的合成/功能化过程中使用不适当的反应环境和忽略DES的基本热性质。最后，提出了一种可选的自下而上框架，用于开发功能和特定任务的DES-ADS。这项工作提供了基于des的吸附剂领域的趋势和轨迹的详细地图，并对该领域内使用的不同方法进行了批判性讨论。根据这种细致的阅读设计的框架是一种系统的，自下而上的方法，考虑了两个领域的原则（吸附和DES）。最终，该框架允许研究人员采取必要的步骤来回答DES-ADS开发需求所带来的研究问题。该框架还可以外推到其他领域，以开发各种基于des的吸附剂，膜或其他功能材料。

期刊介绍： Progress in Materials Science is a journal that publishes authoritative and critical reviews of recent advances in the science of materials. The focus of the journal is on the fundamental aspects of materials science, particularly those concerning microstructure and nanostructure and their relationship to properties. Emphasis is also placed on the thermodynamics, kinetics, mechanisms, and modeling of processes within materials, as well as the understanding of material properties in engineering and other applications. The journal welcomes reviews from authors who are active leaders in the field of materials science and have a strong scientific track record. Materials of interest include metallic, ceramic, polymeric, biological, medical, and composite materials in all forms. Manuscripts submitted to Progress in Materials Science are generally longer than those found in other research journals. While the focus is on invited reviews, interested authors may submit a proposal for consideration. Non-invited manuscripts are required to be preceded by the submission of a proposal. Authors publishing in Progress in Materials Science have the option to publish their research via subscription or open access. Open access publication requires the author or research funder to meet a publication fee (APC). Abstracting and indexing services for Progress in Materials Science include Current Contents, Science Citation Index Expanded, Materials Science Citation Index, Chemical Abstracts, Engineering Index, INSPEC, and Scopus.
