Positively Charged Fluorine-Free Cyclodextrin Nanosponges for PFAS Removal
Chemical diversity and persistence of per- and polyfluoroalkyl substances (PFAS), particularly short-chain variants, pose significant challenges for conventional water treatment.
Structural diversity of cyclodextrin metal-organic frameworks enables their diverse applications
Cyclodextrin-based metal-organic frameworks (CD-MOFs) constitute a distinctive family of porous solids that combine the modularity of coordination networks with the
A supramolecular assembly made with sulfobutylether-β-cyclodextrin and magnetic Fe3O4 showing water remediation properties
In this paper, a magnetic hybrid system was produced by supramolecular self-assembly between low-cost precursors: the sulfobutylether-β-cyclodextrin (SBECD) and magnetic
β–Cyclodextrin polymerization for selective separation of long-chain per- and poly-fluorinated alkyl substances at environmentally relevant concentrations
Per- and polyfluorinated alkyl substances (PFASs), especially long-chain compounds such as perfluorooctanoic acid (PFOA), perfluorooctanesulfonic acid (PFOS), perfluorononanoic acid (PFNA),
Recent progress on the porous cyclodextrin polymers in water treatment
Cyclodextrin plays a positive role in water treatment due to its hydrophobic cavity that can capture organic pollutants. However, non-porous
A super-efficient gel adsorbent with over 1000 times the adsorption capacity of activated carbon
It was observed that a super-efficient gel adsorbent system (RRQG@CDC) could be obtained when a matrix material of polyquaternium gel
Chemical Tailoring of β-Cyclodextrin-Graphene Oxide for Enhanced Per- and Polyfluoroalkyl Substances (PFAS) Adsorption from Drinking Water
Nowadays, per- and polyfluoroalkyl substances (PFAS) are used in hundreds of thousands of industrial products, i.e. food packaging, paints, cosmetics,
Cyclodextrin-based strategies for removal of persistent organic pollutants
Among water contaminants, persistent organic pollutants (POPs) were widely spread during the last few decades and are now present all
Cyclodextrin-functionalized iron oxide nanoparticles for extracting nanometallic pollutants from water
Extraction of Au/Ag nanoparticles (NPs) as nanometallic pollutants from an aqueous phase was carried out using cyclodextrin (CD)-stabilized magnetic NPs.
