Special Issue Information

Dear Colleagues,

Environmental contamination by pollutants and heavy metals poses severe threats to ecosystems and human health globally. Understanding the fate, transport, and transformation mechanisms of pollutants—including heavy metals, microplastics, pesticides, and emerging contaminants—is critical for effective mitigation. This Special Issue invites original research and reviews addressing the complex behaviors of pollutants in soil, water, and air systems, and innovative bioremediation strategies leveraging microorganisms, plants, or enzymes. We seek studies on the following:

  • Pollutant dynamics: Bioaccumulation, persistence, degradation pathways, and interactions with environmental matrices.
  • Advanced bioremediation: Genetic engineering of microbial consortia, phytoremediation enhancements, and enzyme-based degradation.
  • Synergistic technologies: Integration of bioremediation with nanotechnology, electrokinetics, or AI-driven monitoring.
  • Ecotoxicological impacts: Long-term effects on biodiversity and ecosystem resilience. 

Therefore, it is my pleasure to invite you to contribute your research article, communication, or review that advances the science and practical deployment of these green technologies for a cleaner, safer planet.

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. Separations is an international peer-reviewed open access monthly 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.

Chlorinated aliphatic hydrocarbons (CAHs) are some of the most widely distributed organic pollutants in underground environments and have high biological toxicity. This research aims to prepare an effective adsorbent comprising biochar and magnetite (MBC) to remove CAH pollution from soil. Optimization of the preparation and adsorption performance of MBC was investigated. The results of the adsorption experiment, combined with scanning electron microscopy (SEM) observations, show that the best raw material and pyrolysis temperature were coconut shell and 500 °C respectively. The Fourier transform infrared (FTIR) and X-ray diffraction (XRD) pattern characterizations, as well as the adsorption results, demonstrated the successful synthesis and enhancement effect of MBC for CAHs. The adsorption of CAHs on Fe3O4-loaded biochar was improved by 34.40–222.25% during pyrolysis at 500–900 °C. Additionally, MBC with a 10% Fe3O4 content had the best effect on three types of CAHs at low concentrations. A comparative pore analysis of MBC with different doses of Fe3O4 was carried out to reveal the relationship between the pore characteristics and adsorption properties. Furthermore, competitive adsorption experiments demonstrated that 4 wt% MBC addition significantly reduced the soil-bound TCE by 48.6%. Overall, these results indicated that MBC was an effective adsorbent for CAH removal from the polluted underground environment. Full article
