Abstract
Compositions and methods are provided for assessing the presence or absence, and optionally quantitating, the surface loading of a noble metal such as platinum on the surface of a substrate. The invention utilizes the decomposition rate of hydrogen peroxide (HO) or other redox active molecule following exposure to the substrate surface to effectively establish a qualitative or quantitative correlation between the redox agent survival fraction and the presence or absence of noble metal (e.g., platinum), and further, for the quantitation of noble metal loading on the substrate surface. The invention finds applicability in assessing the surface loading of noble metals on the internal surfaces of boiling water nuclear reactor plants (BWR) that have undergone prior noble metal application.
