Special Issue Information

Dear Colleagues,

You are cordially invited to contribute original research papers or reviews to this Special Issue of Molecules, which will report on sustainable sources of algal biomass and seaweeds for the bioremediation of heavy metals in wastewater. The bioremediation of heavy-metal-contaminated effluents represents a major challenge for the wastewater treatment industry. Under optimized conditions, algal biomass can sequestrate up to hundreds of milligrams of metal per gram of biomass; this high biosorption capacity has been receiving industrial interest. However, producing an economical and sustainable algal bioremediation process for heavy metal removal will rely heavily on the appropriate algal biomass, supply, reuse, and metal recovery. This Issue primarily focuses on algal biomass pre-treatment, immobilization, and factors affecting biosorption capacity, such as wastewater quality, initial metal ion concentration, biomass concentration, initial pH, time, temperature, and interference of multiple metal ions. Submissions related to the optimization of low-cost algal biomass for high bioremediation potential will be encouraged.

Manuscript Submission Information

Manuscripts should be submitted online at 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 papers will be 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 2000 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.
