Quantitative X‐Ray Fluorescence Imaging to Evaluate the Efficacy of Micro‐Structured Cellulose Foams and Poultices in Wall Painting Desalination

open access: yesChemistry–Methods, Volume 6, Issue 1, January 2026.
This work assesses, through a quantitative micro energy dispersive X‐ray fluorescence imaging, the effective use of micro‐structured cellulose foams as a sustainable alternative to traditional poultices for desalinating fresco paintings. Foams were between 6 and 10 times more efficient, achieving rapid and in‐depth salt removal with reusability and ...
