Abstract
The mercury detecting paper provides a visual indication of the presence of mercury in an applied water sample. The mercury detecting paper is formed as a hydrophobic substrate having a reagent layer deposited thereon. The hydrophobic substrate is made from paper having a layer of hexamethyldisilazane (HMDS) deposited thereon, and the reagent layer is a layer of 6-hydroxy-3-(2-oxoindolin-3-ylideneamino)-2-thioxo-2H-1,3-thiazin-4(3H)-one (HOTT). In use, a water sample is applied to the reagent layer and a visual color change of the reagent layer upon contact with the water sample indicates a presence of mercury in the water sample. Specifically, HOTT turns a brick red color upon contact with Hgions.
