About Sodium Selenite

Sodium selenite (Na₂SeO3) is a colourless, water-soluble inorganic compound containing the trace element selenium. It is commonly used in the manufacture of colourless glass to neutralise green impurities. Sodium selenite is also an ingredient in dietary supplements and animal feeds due to selenium's essential role in human and animal health. However, it can be toxic in high concentrations.

In 1889, Irish chemists Sir Charles A. Cameron and John Macallan produced sodium selenite by heating selenium oxide with sodium chloride. In 1929, J. B. Krak at the Roessler and Hasslacher Chemical Co. prepared sodium selenite by evaporating a solution of sodium hydroxide and selenious acid. However, commercial sodium selenite is now made by heating an aqueous solution of selenium dioxide and sodium hydroxide to form the pentahydrate, which is then warmed to 40 °C to obtain the anhydrous salt.

Properties of Sodium Selenite

Sodium selenite (Na₂SeO₃) is a colourless, crystalline solid with a molar mass of 172.95 g/mol. It has a density of 3.1 g/cm cube and decomposes at 710 °C. It is highly soluble in water (85 g/100 mL at 20 °C) but is insoluble in organic solvents like ethanol. Chemically, sodium selenite acts as an antioxidant and plays a role in metabolic enzyme regulation. Its crystal structure can be tetragonal or monoclinic, and it is known for its potential antineoplastic activity, making it significant in cancer research.

Manufacturing Process of Sodium Selenite

The production of sodium selenite begins with the dissolution of selenium dioxide (SeO₂) in water, typically in a steel basin. Sodium hydroxide (NaOH) is then gradually added to the solution, adjusting the pH to between 7 and 14 while stirring. Afterward, additives and adsorbents are introduced, and the mixture is stirred for several hours before being filtered to remove impurities. The clear solution is heated to evaporate water, promoting supersaturation and crystallisation of sodium selenite. Finally, the crystals are dehydrated in a centrifuge, dried in an oven at 120 °C, and crushed to obtain the final product.

Synthesis of Sodium Selenite

The production of sodium selenite typically involves the following steps:

1. Oxidation of Selenium

The first step in the production of sodium selenite is the oxidation of elemental selenium (Se) to selenium dioxide (SeO₂). This is typically achieved by roasting selenium in the presence of oxygen. The chemical reaction involved is as follows:

Se (s) + O₂ (g) → SeO₂ (s)

In this reaction, selenium is oxidised by oxygen to form selenium dioxide, a white solid.

2. Dissolution in Sodium Hydroxide

The selenium dioxide (SeO₂) is then dissolved in a solution of sodium hydroxide (NaOH) to produce sodium selenite. The chemical reaction is as follows:

SeO₂ (s) + 2NaOH (aq) → Na₂SeO₃ (aq) + H₂O (l)

In this reaction, selenium dioxide reacts with sodium hydroxide to form sodium selenite (Na₂SeO₃) in solution, along with water.

3. Crystallisation

The sodium selenite solution is then concentrated by evaporation, leading to the crystallisation of sodium selenite. The crystallised Na₂SeO₃ is collected and dried to obtain the final product.

4. Final Processing and Packaging

The dried sodium selenite crystals are subjected to final processing, which may include grinding to obtain a specific particle size. The product is then packaged and prepared for distribution, ready for use in various applications.

Applications and Drivers of Sodium Selenite

Sodium selenite has diverse applications, primarily in glass manufacturing, where it is used to remove green hues caused by iron impurities, resulting in colourless glass. It is also used as a dietary supplement due to selenium's essential role in human health, often included in multivitamins and animal feeds to prevent selenium deficiencies, particularly in livestock like swine and poultry. Additionally, sodium selenite serves as a reagent in various chemical analyses, including bacteriology and plant growth studies, enhancing antioxidant properties and overall plant health. The growing demand for selenium in dietary supplements and its applications in agriculture and glass production are key drivers of the sodium selenite market growth.
