Special Issue Information

Dear Colleagues,

Interest in the research of clean water is basically supported by the fact of its high consumption by human beings for diverse applications and, thus, every single person should be able to access clean water. Consequently, wastewater treatment and purification processes are being deeply studied. In this regard, recently developed polymer-based materials are gaining much importance and interest from researchers. Their large surface area, greater functionalities, nontoxic nature and biodegradability are a few of the properties of polymer-derived materials that make them the candidate of choice to be explored in the field of wastewater treatment. Inorganic and organic polymers as well as biopolymers are explored in the fabrication of hydrogels, filtration membranes, ion exchangers and nanocomposites specifically designed for wastewater remediation. New composite polymeric materials are mainly responsible for these great advances. Thus, it becomes of immense important to design, investigate and explore each aspect of polymer-based advance materials, including their structural modification, physiochemical properties and potential applications in context of environmental detoxification specifically for wastewater treatments.

This Special Issue is dedicated to research papers and reviews on the following topics:

  1. Recent polymeric materials for adsorption of pollutants.
  2. Polymer-based membranes for water purification.
  3. Hydrophobic and/or hydrophilic interactions in polymers with potential use in water treatment.
  4. Polymeric hydrogels for elimination of pharmaceuticals waste from industrial effluents.
  5. Nanocomposite materials possessing a polymeric matrix as support.
  6. Interactions of diverse pollutants such as metal ions, dyes, phenols and pesticides with polymeric materials.
  7. Polymeric photocatalysts for degradation of organic pollutants.
  8. Polymeric composite ion exchangers.
  9. Advanced polymeric materials for elimination of harmful microorganisms from aqueous mediums.
  10. Inorganic polymeric materials: characterization and application in wastewater treatment.
  11. Modification of natural polymers for environmental remediation. 

We would be please if you would join us in contributing to this Special Issue.

The escalating demand for rare earth metals (REM) in situations of limited availability has spurred scientists to seek alternative sources of REM, such as industrial waste solutions. This paper investigates the potential for improving the sorption activity of readily available and inexpensive ion exchangers, specifically the interpolymer systems “Lewatit CNP LF and AV-17-8”, towards europium and scandium ions, in comparison to the unactivated ion exchangers. The sorption properties of the improved sorbents (interpolymer systems) were evaluated using conductometry, gravimetry, and atomic emission analysis. The results demonstrate that the “Lewatit CNP LF:AV-17-8” (5:1) interpolymer system exhibits a 25% increase in europium ion sorption compared to the raw Lewatit CNP LF (6:0), and a 57% increase in europium ion sorption compared to the raw AV-17-8 (0:6) ion exchanger after 48 h of the sorption process. In contrast, the “Lewatit CNP LF:AV-17-8” (2:4) interpolymer system exhibits a 310% increase in scandium ion sorption compared to the raw Lewatit CNP LF (6:0), and a 240% increase in scandium ion sorption compared to the raw AV-17-8 (0:6) after 48 h of interaction. The improvement in europium and scandium ion sorption levels by the interpolymer systems, compared to the raw ion exchangers, may be attributed to the high ionization degree resulting from the remote interaction effect of the polymer sorbents as the interpolymer system in aqueous media.

Abstract
This study investigated the effect of the remote activation of the ion exchangers Amberlite IR120 (H+ form) and AV-17-8 (OH− form) in aqueous media to increase the sorption activity of the interpolymer system “Amberlite IR120H:AV-17-8” (X:Y, molar ratio of ionic groups) [...] Read more.
This study investigated the effect of the remote activation of the ion exchangers Amberlite IR120 (H+ form) and AV-17-8 (OH− form) in aqueous media to increase the sorption activity of the interpolymer system “Amberlite IR120H:AV-17-8” (X:Y, molar ratio of ionic groups) towards cerium ions from uranium-containing solutions. The sorption properties of the above-mentioned interpolymer system with molar ratios X:Y of 6:0, 5:1, 4:2, 3:3, 2:4, 1:5, and 0:6 were studied using the methods of conductometry, gravimetry, and inductively coupled plasma–optical emission spectrometry. The presented research revealed the dependence of the sorption activity of the interpolymer system “Amberlite IR120H:AV-17-8” (X:Y) on the acidity of the solution. At pH 2.0, the highest cerium ion sorption degree from the model solution (containing both cerium and uranium ions) by the interpolymer system “Amberlite IR120H:AV-17-8” (4:2) was 56% after 48 h of interaction, whereas the cerium ion sorption degrees by raw Amberlite IR120H (6:0) and raw AV-17-8 (0:6) were 30% and 0%, respectively. The increased sorption ability of the interpolymer system “Amberlite IR120H:AV-17-8” (4:2) might be associated with the achievement of the highest ionization degree by this system remotely activated in an aqueous medium. Moreover, the cerium ion desorption study demonstrated a 60% degree of desorption using 2M nitric acid as a desorbing agent (eluent). The obtained results demonstrate the potential of using the remote interaction effect for the activation of the ion exchangers in aqueous media as an interpolymer system for increased cerium ion sorption from uranium-containing solutions.
