Application


  • Denitrification mechanism of NaOH in the presence of carbon.: Explores the interaction between sodium carbonate and other chemicals in environmental applications, particularly focusing on denitrification processes important for water treatment (Li et al., 2005).

  • Evaluation of capillary electrophoresis for determining the concentration of dissolved silica in geothermal brines.: Discusses the role of sodium carbonate in modifying sample pH for capillary electrophoresis, essential for accurate measurement of silica in complex geothermal fluids (Santoyo et al., 2005).

Biochem/physiol Actions
