Sulfadimethoxine sodium is a sulfa drug that is an amide form of sulfadiazine. It is used to treat bacterial infections, such as urinary tract infections, septicemia, and infections of the skin and soft tissues. Sulfadimethoxine sodium can be used in wastewater treatment because it has been shown to cause cell lysis and inhibit microbial growth. The chemical structure of sulfadimethoxine sodium consists of two parts: a sulfonamide group and a carbonate group. It also contains four hydrochloric acid molecules in its molecular structure. The experimental model for human serum is found by adding the salt to human serum at a ratio of 1:1. This process leads to the formation of hydrogen ions and carbon dioxide gas bubbles, which causes the solution to become acidic.
