Nanofiber PVA‐Based Membranes Incorporating Functionalized Spanish Broom Derivatives for Sustainable Water Purification

open access: yesENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 6, November 2026.
This study investigates Spanish broom (Spartium junceum) as a renewable source for electrospun composite membranes in sustainable water purification. MCC and biochar were functionalized with eco‐friendly precursors and nanomaterials (i.e., HNT, β‐CDs) to develop hybrid PVA nanofiber composites.

Sustainable and Efficient Removal of Organic Dyes From Water Using a Graphene Oxide‐Conjugated PEGylated Polystyrene Resin

open access: yesJournal of Applied Polymer Science, Volume 143, Issue 40, October 20, 2026.
A graphene oxide‐functionalized PEGylated polystyrene (PS‐PEG@GO) resin is developed as a recoverable, reusable adsorbent for cationic dye removal from water. Combining efficient multi‐dye adsorption with simple filtration‐based recovery and stable reuse, it retains over 90% removal for CV and MB and 89.19% and 85.15% for R6G and RB after 20 cycles ...

Freundlich Adsorption Isotherms of Adsorbent from H3PO4 and ZnCl2 Treated Irish Potato Peels [PDF]

open access: yes, 2013
Activated carbon from irish potato peels, treated with H3PO4 and ZnCl2 were prepared using the one and two stage processes. The study was designed to model the adsorption of a dye, methylene blue, using the Freundlich isotherm model.
