Classification: CPC G | IPC G

Claim 0:
1. A method for rapid detection of actinides, the method comprising:
a) having a support including a colorimetric complexation, wherein the colorimetric complexation is a hybrid combination of 2-(5-Bromo-2-pyridylazo)-5-(diethylaminolphenol (Br-PADAP) and 1-(2-Pyridylazo)-2-naphthol (PAN), the colorimetric complexation configured to activate when contacted by at least one actinide;
b) placing the support in communication with a sample through urinalysis, the sample having an unknown concentration of at least one actinide within it;
c) activating the colorimetric complexation when contacted by the at least one actinide, and
d) receiving one or more visual indicators from the colorimetric complexation on a condition that the sample contains at least a threshold concentration of the actinide, the visual indicators including a first visual indicator that is configured to produce a purple color on reaction with the sample on a condition that the sample contains at least a threshold concentration of uranium and a second visual indicator that is configured to produce a non-purple color on reaction with the sample on a condition that the sample contains at least a threshold concentration of an actinide that is plutonium, the first visual indicator and the second visual indicator being visible to a naked eye.
