Abstract
A composition of matter includes water, at least one acid, at least one surfactant, at least one fluoride salt, and ammonium nitrate. A method of decontaminating a surface includes exposing a surface to such a composition and removing the composition from the surface. Other compositions of matter include water, a fatty alcohol ether sulfate, nitrilotriacetic acid, at least one of hydrochloric acid and nitric acid, sodium fluoride, potassium fluoride, ammonium nitrate, and gelatin.
Claims25
A composition, comprising:
- water;
- at least one chelator selected from the group consisting of ethylenediaminetetraacetic acid, (2-hydroxyethyl)ethylenediaminetriacetic acid, ethylene glycol-bis-(2-aminoethyl)-tetracetic acid, ammonium molybdophosphate, and nitrilotriacetic acid;
- at least one of hydrochloric acid or nitric acid;
- at least one surfactant comprising a fatty alcohol ether sulfate;
- at least one fluoride salt;
- and
- ammonium nitrate.
A composition, comprising:
- water;
- a fatty alcohol ether sulfate;
- nitrilotriacetic acid;
- hydrochloric acid;
- sodium fluoride;

A composition consisting essentially of:
- water;
- a fatty alcohol ether sulfate;
- nitrilotriacetic acid;
- hydrochloric acid;
- sodium fluoride;
- corn starch;
- citric acid;
- ammonium nitrate;
- potassium fluoride;

A method of decontaminating a surface, comprising:
- exposing a surface to a composition, the surface having a radioactive contaminant material thereon and the composition comprising:
- water;
- at least one acid;
- at least one surfactant;
- at least one fluoride salt;
- and
- ammonium nitrate;
- and
- removing at least a portion of the composition from the surface to remove at least a portion of the radioactive contaminant material from the surface.
