General description

Sodium carbonate is usually referred to as soda ash. Solvay process uses sodium chloride and limestone to produce sodium carbonate.[24] Sodium carbonate enhances the pretreatment of rice straw and enhances delignification process.[30] Sodium carbonate finds its application in the extraction of bioactive metabolites like epoxyditerpenoids and alkaloids and removes acidic compounds from the extract.[52] Sodium carbonate induces the phase separation in salt induced phase separation extraction (SIPSE) method and enhances the plasma partitioning with acetonitrile.[38]

Application

Sodium carbonate has been used:
  • to stop α-glucosidase enzyme activity using the extract of Terminalia species
[28]
  • as a component in carbonate/bicarbonate buffer for enzyme linked immunosorbent assay (ELISA)
  • [29]
  • as a component in the growth medium for Synechocystis strains
  • [30]
