Eosin Yellow Sodium Salt, commonly known as Eosin Y, is used in environmental and microbiological research. It is essential to staining techniques as a biological stain, helping to identify and make microorganisms visible under a microscope.
To examine and analyze the morphology and structure of microorganisms, scientists relied on this staining capability in their microbiological research.
The ability to form a distinct complex with copper ions allows for the detection and quantification of copper levels in a range of environmental samples.
Furthermore, Eosin Y works well as a wastewater treatment agent when paired with benzalkonium chloride. This mixture supports environmental cleanup initiatives by assisting in the removal of pollutants and pathogens from wastewater and enhancing water quality.
