Abstract
The present development is a kit and a method for easily determining the presence of lead on a surface. The kit provides a rhodizonate salt and an aqueous acid mixed together in a container that can deliver a liquid product as a fine particle spray. In a preferred embodiment, the rhodizonate salt is sodium rhodizonate and the aqueous acid is aqueous acetic acid. The method includes mixing sodium rhodizonate and aqueous acetic acid and then delivering it to a surface as a fine particle spray, and monitoring any change of color on the treated surface.
