Special Issue Information

Dear Colleagues,

The Special Issue “Functional Polymers in Separation Science” is dedicated to exploring the wide-ranging applications of functional polymers in the field of separation science, with a particular focus on their chemical attributes and separation efficiency. Functional polymers, distinguished by their unique chemical structures and physical properties, have become pivotal tools in the realm of separation tasks. This Special Issue centers on unveiling the design, synthesis, characterization, and cutting-edge developments of polymers across various applications.

Our Special Issue delves into the following key themes:

  • Tailored design of functional polymers: This encompasses the rational design of molecular structures, cross-linking degrees, and functional groups to optimize separation performance.
  • Methods for the preparation and synthesis of functional polymers: Introduce innovative synthesis techniques, such as controlled polymerization, self-assembly, and the integration of nanomaterials, for the fabrication of polymers with unique properties.
  • Applications of functional polymers in separation processes: Explore the applications of functional polymers in separation sciences, including liquid-phase chromatography, gas-phase chromatography, membrane separation, ion exchange, affinity separation, and more.
  • Applications of functional polymers in biotechnology and life sciences: Investigate the roles of these materials in bioprocessing, drug delivery, protein purification, and bioanalysis.
  • Applications of functional polymers in environmental and energy fields: Emphasize the innovative uses of functional polymers in wastewater treatment, waste recycling, and energy production.

This Special Issue aims to provide a comprehensive platform for researchers to gain insights into how functional polymers can enhance separation efficiency and address critical societal challenges. We look forward to researchers from around the world sharing their latest findings and contributing to the forefront of research and applications in functional polymers in the field of separation science.

The recovery of Au(III) from solution using adsorbents in the form of granules or powders is challenging due to issues such as instability during the recovery process or mass loss caused by small particle size. This study introduces a PEI-TCT/PVDF composite membrane designed to intercept and capture Au(III) in wastewater. Experimental results demonstrated that the PEI-TCT/PVDF membrane exhibits a broad pH range (1–8) and a high retention efficiency for Au(III) of 97.8%, with a maximum adsorption capacity of 294.5 mg/g. The mechanism of Au(III) adsorption on the PEI-TCT/PVDF membrane was mainly through electrostatic adsorption, which caused AuCl4− to aggregate on the surface of the membrane and gradually reduced to Au0 and Au+. Furthermore, the membrane can be entirely regenerated within 20 min and maintains its performance in subsequent adsorption cycles. This study highlights the potential of PEI-TCT/PVDF membranes for the recovery of precious Au(III). Full article

Aquatic environments face contamination by pharmaceuticals, prompting concerns due to their toxicity even at low concentrations. To combat this, we developed an ecologically sustainable biosurfactant derived from a microorganism and integrated it into bacterial cellulose (BC). This study aimed to evaluate BC’s efficacy, with and without the biosurfactant, as a sorbent for paracetamol and 17α-ethinylestradiol (EE2) in water. We cultivated BC membranes using Gluconacetobacter xylinus ATCC 53582 and synthesized the biosurfactant through pre-inoculation of Bacillus subtilis in a synthetic medium. Subsequently, BC membranes were immersed in the biosurfactant solution for incorporation. Experiments were conducted using contaminated water, analyzing paracetamol concentrations via spectrophotometry and EE2 levels through high-performance liquid chromatography. Results indicated BC’s superior adsorption for EE2 over paracetamol. Incorporating the biosurfactant reduced hormone adsorption but enhanced paracetamol sorption. Notably, original and freeze-dried BC exhibited better adsorption efficacy than biosurfactant-infused BC. In conclusion, BC showed promise in mitigating EE2 contamination, suggesting its potential for environmental remediation. Future research could focus on optimizing biosurfactant concentrations to enhance sorption capabilities without compromising BC’s inherent effectiveness. Full article
