Abstract
Official abstract text for this publication.
A method for rapid detection of actinides including the steps of having a support including a colorimetric complexation, placing the support in communication with a sample, and receiving a visual indicator from the colorimetric complexation. The sample having an unknown concentration of at least one actinide within it. The colorimetric complexation is configured to activate when contacted by a threshold concentration of an actinide.
First claim
Opening claim text (preview).
1 ) A method for rapid detection of actinides, the method comprising: a) having a support including a colorimetric complexation, the colorimetric complexation configured to activate when contacted by a threshold concentration of at least one actinide; b) placing the support in communication with a sample, the sample having an unknown concentration of at least one actinide within it; and c) receiving a visual indicator from the colorimetric complexation when the sample contains at least a threshold concentration of the actinide. 2 ) The method of claim 1 , wherein the colorimetric complexation can detect actinides present in a concentration on the order of parts-per-billion. 3 ) The method of claim 1 , wherein the colorimetric complexation will activate when contacted by at least one actinide. 4 ) The method of claim 3 , wherein the colorimetric complexation activation is unique to different combinations of potentially present actinides. 5 ) The method of claim 1 , wherein the colorimetric complexation is a 2-(5-Bromo-2-pyridylazo)-5-(diethylamino)phenol (Br-PADAP) mixture. 6 ) The method of claim 1 , wherein the colorimetric complexation is a hybrid combination of 2-(5-Bromo-2-pyridylazo)-5-(diethylamino)phenol (Br-PADAP) and 1-(2-Pyridylazo)-2-naphthol (PAN). 7 ) The method of claim 1 , wherein the colorimetric complexation is an isoamethurin mixture. 8 ) The method of claim 1 , wherein the colorimetric complexation is a dithizone mixture. 9 ) The method of claim 1 , wherein the colorimetric complexation is a pyridylazo mixture. 10 ) The method of claim 1 , wherein the support is a liquid that can be used as a spray. 11 ) The method of claim 1 , wherein the support is a pod. 12 ) The method of claim 1 , wherein the support is a wipe. 13 ) The method of claim 1 , wherein the support is a gel. 14 ) The method of claim 1 , wherein the support is capable of providing test results for different actinides. 15 ) The method of claim 1 , wherein the sample is either a solid, a liquid, or a combination of a solid and a liquid. 16 ) The method of claim 1 , wherein the sample is first separated from contamination. 17 ) The method of claim 1 , wherein the visual indicator is received within a predetermined amount of time. 18 ) The method of claim 17 , wherein the predetermined amount of time is within approximately 5 minutes. 19 ) The method of claim 1 , further comprising repeating the steps a-c at least one time. 20 ) The method of claim 1 , wherein the method is implemented in response to a radiological incident.
