Summary: A membrane consisting of a composite of polyethylene terephthalate nanofiber and multi-walled carbon nanotubes is used to adsorb methylene blue dye from an aqueous solution. The study examines the surface properties of the adsorbent and optimizes parameters such as pH, dye concentration, adsorbent dose, and contact time for efficient removal. The results show that pH has the highest impact on removal efficiency, followed by adsorbent dose, dye concentration, and contact time. The Langmuir isotherm and pseudo-second-order kinetic model are well-suited to describe the adsorption process.

Summary: Recently, new knowledge has been gained in the field of water treatment through the use of deep eutectic solvents (DESs) for functionalization and synthesis of adsorbent materials. This review highlights the improvements made in functionalizing adsorbents using DESs, with a focus on the removal of micropollutants, dyes, heavy metals, and other contaminants from aqueous systems. The study describes the base materials used for DES-based synthesis and functionalization of adsorbents, their physicochemical characteristics, and the target chemicals and removal efficiency in water treatment applications. DESs have shown promising results in enhancing pollutant removal through increased surface area and introduction of desired functionalities. They can be applied during or after the production of adsorbent materials.

Summary: This study evaluates the potential environmental impacts of a representative choline chloride (ChCl)/urea deep eutectic solvent (DES) called reline, using life-cycle assessment (LCA). The results show that reline has lower environmental impacts compared to certain organic solvents, but higher impacts compared to methanol and ethanol. The chemical constituent materials used in the synthesis of reline DES contribute significantly to its life-cycle environmental impacts. Additionally, LCA is performed on four other ChCl-based DESs, with ChCl/citric acid DES showing the highest environmental impacts.
