Abstract
Strippable coating is a low cost and efficient decontamination method far more compatible for
the cleaning of surfaces. This method allows contaminant entrapment and removal from different
types of surfaces and also characterized by low-secondary waste generation after
decontamination. The present work deals with the elaboration and testing of a new composition
of Polyvinyl alcohol (PVA) aqueous solutions utilize the TTA (Thenoyl trifluoroacetone)
ligand , employed as a strippable coating for the removal of metal ions e.g., UO2
+2, Ni+2, Cu+2, Fe+3, V+5, Eu+3 and Cs+
from "contaminated" surfaces. The study aims at developing
contaminant-sensing and decontaminating coatings for the detection and removal of metal ions
from non porous surfaces. This “smart” coating is shown to exhibit a clear contaminant
dependent response in the form of color variation, and a detection sensitivity less than 0.5g per
cm2
.
