Sodium nitrite (NaNO2) is an important nitrite salt widely used in various industries, including food, pharmaceuticals, and chemicals. The conventional method for sodium nitrite extraction involves the reaction of nitrite ions with sodium chloride (NaCl) and sodium hydroxide (NaOH) in aqueous solution. This article provides an overview of the conventional method for sodium nitrite extraction, including the reaction mechanism, process optimization, and industrial applications.
