Special Issue Information
Dear Colleagues,
Due to persistent industrialization and anthropic action, water remediation will always be a challenge. It is therefore crucial to develop new technologies for the treatment of contaminated water resources. Sorption, as an efficient and well-structured method for the remediation of water resources, requires the development of new sorbents highly efficient at removing different classes of contaminants, given the increasingly complex composition of waste discharged into water resources. It is desirable, however, to use natural-based sorbents, specifically those that promote the reuse of waste and discharged materials, as opposed to conventional/synthetic sorbents that are relatively expensive and laborious to produce and less environmentally friendly. Recent published papers have demonstrated the good performance and versatility of natural-based sorbents for removing a large variety of contaminants. It is therefore advisable to further explore the knowledge on this kind of material.
In this regard, the present Special Issue focuses on experimental studies concerning the preparation and use of natural-based sorbents and that cover the following topics: (a) natural sorbents, e.g., from mineral waste and vegetal or animal biomass, with or without physical and chemical modification; (b) removal of organic or inorganic contaminants from water; (c) physical and chemical characterization of the sorbent; (d) kinetic and equilibrium sorptive tests with the aim of verifying the optimum conditions for pollutant uptake, exploring the effect of reaction time, pH, sorbent dosage, concentration, and temperature; (e) evaluation of thermodynamic and kinetic parameters; and (f) determination of the actual sorption mechanism.

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 100 words) can be sent to the Editorial Office for announcement on this website.
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. Molecules 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 2700 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.
