摘要: Wipes, methods and kits useful for testing and/or removal of metal from surfaces (such as, dermal surfaces) are disclosed. Exemplar wipes, including the combination of a three-dimensionally textured absorbent support, a cationic surfactant, and a weak acid, are disclosed. In some examples, the cationic surfactant is isostearamidopropyl morpholine lactate (ISML), and the weak acid is citric acid.

摘要: A method of detecting lead contamination of a surface is disclosed. A handwipe issued to collect any lead contamination on the surface. The lead is solubilized with an aqueous acid solution and treated with rhodizonate or sulfide anions. A change in color from pink to red, where rhodizonate anions are used, or brown to black, where sulfide anions are used, is indicative of the presence of lead. The method is suitable for testing surfaces such as floors, walls, windowsills, and human skin.
