Special Issue Information

Dear Colleagues,

In this Special Issue, we want to emphasize new materials with nanomeric sizes, whose extraordinary properties allow for their use as adsorbents. Specifically, the adsorption of pollutants in water and aquatic environments at very low concentrations requires the use of more demanding techniques to achieve their elimination, and nanostructured materials can be an alternative to conventional techniques. For these reasons, the manufacture of these materials and their characterization are of the utmost importance in separation techniques.

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 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. Separations 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 1800 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.

This work presents a novel procedure for the removal of Cu2+ from water, an essential element in human nutrition considered toxic in high concentrations, based on a microextraction technique involving the formation of a micellar phase. To achieve the total elimination of copper from aqueous samples, a Cu2+-complexing reagent based on silver nanoparticles functionalized with sodium mercaptoethane sulfonate ([email protected]) was used. The complex formed by Cu2+ and the reagent was extracted into a micellar microphase formed by Triton X-114, a harmless surfactant. Volumes of 200 µL of the 10−4 mol L−1 suspension of [email protected] and 100 µL of a solution of Triton X-114 at 30% m/m were employed to successfully remove 10 mg L−1 of Cu from 20 mL of water samples. The time and temperature needed to achieve 100% microextraction efficiency were 10 min and 40 °C, respectively. The procedure is considered environmentally friendly due to the low volume of the extracting phase and the simple experimental conditions that achieve total removal of Cu2+ from water samples.

Title: Synthesis of new nanostructured materials as adsorbents for pollutants in waters
Authors: Yesica Vicente-Martínez; Manuel Caravaca-Garratón; Antonio Soto-Meca; Carmen M. García-Onsubre

Abstract: Numerous materials are employed as adsorbents for pollutants in waters, but in recent years nanostructured materials have experienced an increase in popularity due to their numerous features and potential advantages. In this paper, we exhibit the synthesis and characterization of various novel materials based on magnetic nanoparticles and graphene as the main nucleus, and functionalized with different complexing agents, which provides versatility to choose the specific pollutant to be adsorbed. Applications include heavy metals, phosphates, nitrates, or emerging pollutants, among others.
