Photocatalytic Degradation of Methylene Blue by Sodium Tungstate
Methylene blue is an aromatic heterocyclic compound, used as a chemical indicator, dye, biological dye and drug use, mostly dyes, the methylene blue aqueous solution is blue in an oxidizing environment. In industrial applications, methylene blue also produces wastewater which is difficult to degrade. The methylene blue wastewater discharged into rivers, lakes and seas is also a toxic substance. Then, how to degrade methylene blue wastewater? In theory, the key and core of difficult wastewater treatment technology is the removal of refractory and insoluble matter in wastewater, that is, how to convert non biodegradable soluble chemicals into biochemical substances. In recent years, with the development of photocatalytic technology, more and more photocatalysts have been developed. Sodium tungstate is one of the most widely used photocatalysts, so is sodium tungstate also suitable for the degradation of methylene blue wastewater? Sodium tungstate is an excellent phot...
