Special Issue Information

Dear Colleagues,

Rapid societal development observed over the past century has resulted in a major increase in environmental contaminants, leading to severe ecological consequences. To mitigate the significant environmental impacts associated with human society’s industrialization, it is critical to develop and use specialized materials—such as advanced adsorbents—which can effectively retain and eliminate pollutants, minimizing the amount discharged into the environment. This Special Issue aims to serve as a comprehensive collection of papers focused on the design, development, preparation, and practical application of adsorbent materials with tailored properties. In the real-world context of water scarcity and intensification of greenhouse gas emissions, these materials represent a pillar of environmental protection. Topics of interest include, but are not limited to, the following:

- Functionalization of traditional adsorbent materials;

- Tailoring adsorbent material surfaces via grating or doping;

- Green synthesis;

- MOFs;

- COFs;

- Selectivity and regenerability of absorbent materials;

- Adsorbent behavior prediction through modeling;

- Advanced characterization of adsorbent materials (SEM, SRD, FT-IR, TEM, etc.);

- Application of such materials.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The environmental challenges posed by heavy metal contamination in sludge leachate are becoming increasingly severe, necessitating the development of highly efficient remediation technologies. Among various treatment approaches, magnetic adsorbents have garnered significant attention as a promising solution due to their outstanding adsorption performance, convenient magnetic separation characteristics, and potential for regeneration. This paper systematically reviews the latest research progress on magnetic adsorbents designed for the complex system of sludge leachate, covering synthesis methods, surface functionalization, adsorption mechanisms, and performance evaluation. Key synthesis strategies are analyzed, including magnetic core preparation, inorganic coating, carbon composites, organic polymer grafting, functional molecule impregnation, and metal–organic framework (MOF) composites. The mechanisms by which these strategies influence material adsorption capacity, selectivity, and stability are elucidated. Despite significant achievements in laboratory studies, practical applications still face challenges such as large-scale synthesis, regeneration efficiency, cyclic stability, and adaptability to complex water bodies. Future research should focus on green synthetic pathways to advance the industrial application of structurally functional magnetic composite materials, providing systematic solutions from material design to process optimization for the sustainable remediation of heavy metal contamination in sludge leachate.
