Abstract
A novel reagent is used to identify arsenic-treated wood. The stain may detect arsenic extracted from wood into solution; arsenic transferred from wood to a wipe, which is then extracted into solution; or the stain may be directly applied at a predetermined location on the wood's surface. Copper preservatives are not detected by the stain and phosphate interference is minimized. The process is quick, inexpensive, and easy to use. Development of a blue color (i.e., reduction of at least some Mo (VI) to Mo (V) in molybdenum blue) indicates the presence of arsenic.
