Special Issue Information
Dear Colleagues,
I am pleased to invite you to submit your recent studies to a Special Issue of Molecules titled “Recent Research Progress of Novel Ion Adsorbents”.
The constant progress of civilization has resulted in the development of many different industries. However, the rapid growth of the human population, industrialization, and excessive use of chemicals have contributed to environmental pollution and a decline in clean water resources. Scientists are still looking for effective, efficient, and economical ways to purify water.
One of these is the adsorption process. Adsorption is a surface phenomenon that, due to attractive forces, enables the accumulation of atoms, molecules, or ions of the adsorbate on the surface of the solid adsorbent. Due to its simplicity, effectiveness, and selectivity, this process is used to remove all unwanted substances from water, such as toxic metals, dyes, pharmaceuticals, pesticides, and others. Moreover, adsorption processes are usually carried out at low temperatures, which makes them energy-efficient and therefore inexpensive. The key to using adsorption processes for effective substance removal is the proper selection and design of adsorption materials. Currently, the most popular adsorbents are activated carbons, clay minerals, zeolite, oxides, as well as organometallic structures, polymeric materials, and composite and functional materials. An ideal sorbent should be highly selective, with high sorption capacity, and good mechanical and thermal stability. On the other hand, the adsorbent must also enable easy adsorbate desorption, regenerate quickly, and must be easily disposable and affordable. These factors also determine the usefulness of the sorbent in practice. Many such factors have a direct impact on adsorption processes. The most important of them include factors related to the adsorbent (specific surface area, functional groups, and purity) and adsorbate (chemical character, charge, and types of functional groups), as well as related to other system properties (pH, type and ionic strength of the electrolyte, temperature, and presence of other substances).
The aim of this Special Issue is to collect the latest literature on the mechanisms of adsorption processes of ionic substances, and the synthesis and characterization of adsorbents used for this purpose. Original research articles, review articles, and short communications describing current research trends and future prospects in the areas of adsorption processes of ionic substances are welcome.

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.
