Summary
Chlorine is used to kill harmful germs in drinking water. However, chlorine can also react with other substances in the water, like dissolved organic matter (DOM), creating unwanted byproducts called disinfection byproducts (DBPs). Phenolic compounds are key parts of DOM that often lead to the formation of DBPs. Because DOM is a highly complex mixture of different compounds, researchers study individual components of DOM like phenol and lignin to understand how DBPs form. This research has been ongoing since the 1970s, resulting in a large body of available scientific data. Machine learning (M
