Special Issue Information
Dear Colleagues,
This Special Issue, entitled “Membrane Systems for Metal Ion Extraction”, is motivated by a growing interest in developing novel selective membranes for metal separation processes. Urban mining refers to the stockpiling of rare metals from discarded electrical and electronic equipment in cities. The separation and recovery of valuable rare metals with high dispersions and low concentrations from urban mining requires highly efficient extraction technology. Thus, for separating rare metals from dilute resources, membrane systems, including with membrane extraction and liquid membranes, have shown significant advantages, owing to their potentially high selectivity and low footprint.
Seawater is another important and largely untapped source of valuable metals. Metals such as boric acid and magnesium chloride should be removed from seawater for water purification. Separation technologies based on sub/nanostructured membranes, i.e., polymer membranes in reverse osmosis and nanofiltration with diameters with narrower than 10 nm, have been developed for metal recovery. These membranes are state-of-the-art for selectivity and stability.
Overall, this Special Issue is orientated to all the above research topics and focused on the latest developments in membrane-based separation processes for metal extraction. Authors are welcome to submit original research papers, communications, and review articles. We look forward to your outstanding contributions for this Special Issue.
Prof. Dr. Michiaki Matsumoto

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. Membranes 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 2200 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.
