Previously we have reported our success in the development of strippable decontaminating coatings for the detection and removal of uranium, plutonium and mercury from contaminated surfaces. We will report our continued progress on the design and development of contaminant-sensing, decontaminating coatings as tools for the decontamination of fouled surfaces. Specifically our recent progress regarding the development of coatings for the detection and removal of lead and americium from a variety of surfaces. The effective decontaminating ability of each coating was determined using atomic absorption spectrosopy, uv-visible spectroscopy, and anodic stripping voltammetry.
