Special Issue Information

Dear Colleagues,

Water pollution represents a significant concern due to the considerable number of emerging contaminants (e.g., additives, pesticides, pharmaceuticals, personal care products, detergents, etc.) generated by different industries, hospitals, domestic sewage, agriculture, etc. These contaminants can be accumulated and are considered as a potential risk for both human health and the environment. An important action is to find new solutions, in principle without secondary effects for the environment, for removal of the contaminants.

In this Special Issue, we invite investigators to contribute original research articles, as well as review articles related to the preparation and characterization of materials and applications of the obtained materials in wastewater treatment. Potential topics include but are not limited to the following:

  • Synthesis and characterization of new materials with potential applications in wastewater treatment;
  • Evaluation of the materials as adsorbents or photocatalytic properties;
  • Application of materials to remove toxic emerging contaminants from wastewaters.

We cordially invite the researchers to submit their latest research articles, reviews, and brief communications that disclose new research in the materials area. Your contributions to this Special Issue are crucial for advancing the frontier of knowledge in the preparations and applications of these materials in wastewater treatment.

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. Materials 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.

Abstract
The aim of this study was to investigate the sorption efficiency of anionic dyes—Reactive Yellow 84 (RY84) and Reactive Black 5 (RB5)—and cationic dyes—Red 46 (BR46) and Basic Violet 10 (BV10)—onto potato peels (Solanum tuberosum L.). The research scope included characterization of [...] Read more.
The aim of this study was to investigate the sorption efficiency of anionic dyes—Reactive Yellow 84 (RY84) and Reactive Black 5 (RB5)—and cationic dyes—Red 46 (BR46) and Basic Violet 10 (BV10)—onto potato peels (Solanum tuberosum L.). The research scope included characterization of the sorbent material (pHPZC, FTIR), the effect of pH on dye sorption efficiency, kinetics (pseudo-first-order and pseudo-second-order models, intraparticle diffusion model), and studies on the sorbent’s maximum sorption capacity (Langmuir 1 and 2, and Freundlich isotherms). The point of zero charge (pHPZC) for potato peels was determined to be pHPZC = 6.43, indicating a slightly acidic character of the material. The sorption efficiency for RB5, RY84, and BV10 was highest at pH 2, while the efficiency for BR46 was highest at pH 6. The time required to reach sorption equilibrium on the tested sorbent increased with the initial dye concentration and ranged from 180 to 270 min for RB5, RY84, and BV10, and from 45 to 210 min for BR46. The maximum sorption capacity of this material was found to be 20.85 ± 0.33 mg/g and 21.63 ± 0.34 mg/g for RB5 and RY84, respectively, and 10.28 ± 0.24 mg/g and 27.15 ± 0.87 mg/g for BV10 and BR46, respectively.
