Wastewater Treatment via the Adsorption Method

Dear Colleagues,

Recent years have witnessed an increased amount of attention on protecting and caring for the environment, related both to legal requirements and to the elimination of hazards that cause direct exposure to human health. Heavy metals can accumulate in living organisms, causing permanent cell damage and disorders leading to disease and even death. Effective ways are still being sought to remove heavy metals from wastewater in those plants where their presence is unfavorable; hence, new techniques are being sought to remove them. The diverse composition of industrial wastewater requires a variety of treatment methods. Heavy metal ions are most often removed by the precipitation of their hardly soluble compounds, most often hydroxides, sulphides, sulphates, and carbonates. In addition to these, ion exchange and sorption methods are widely used.

Sorption as a method of removing contaminants from water and wastewater and recovering valuable metals is the subject of numerous studies. Sorbents for the treatment of contaminated groundwater are currently being sought.

Classical, highly efficient methods of industrial wastewater treatment seem to be insufficient in view of very high concentrations of pollutants in wastewater. Widely used sorption materials can be helpful in removing contaminants.

This Special Issue aims to contribute to the search for new methods of wastewater treatment. We encourage the publication of scientific articles, critical reviews, or case studies that are relevant to environmental protection.

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. Water 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.
