Ammonium sulfite monohydrate is a chemical compound that has been shown to have photocatalytic activity. It has also been found to be soluble in sodium salts and chloride. Ammonium sulfite monohydrate is activated by light and reacts with organic substances in the environment, such as fatty alcohols, which can cause particles to protrude from the surface. The protrusion process continues until the particle is completely covered by the coating material. This coating process can be used for detection of human urine and other organic materials in water samples.
