Sodium 1-Naphthol-8-sulfonate

CAS: 20215-36-5

1-Naphthol-8-sulfonate is an organic ligand that is used as a monomer in coordination chemistry. It binds to metal ions and forms a coordination complex. 1-Naphthol-8-sulfonate has been shown to adsorb onto hydrophobic surfaces such as polystyrene, which is why it is used in wastewater treatment. The spontaneous reaction of 1-naphthol and sodium sulfite results in the formation of 1-naphthol-8-sulfonate with a spontaneous reaction rate that increases with increasing concentration of hydrophobic ligands. This product can be used for removing pollutants from wastewater because it adsorbs to the hydrophobic surfaces of microorganisms and removes them from the water.
