Sodium bicarbonate is an important component and additive in the preparation of many other chemical raw materials. Sodium bicarbonate is also used in the production and treatment of various chemicals, such as natural PH buffers, catalysts and reactants, and stabilizers used in the transportation and storage of various chemicals.
3. Metal industry applications
The application of environmental protection is mainly in the discharge of "three wastes". Such as: steelmaking plant, coking plant, cement plant tail gas desulfurization should use sodium bicarbonate. Waterworks use sodium bicarbonate for primary purification of raw water. Waste incineration requires the use of sodium bicarbonate and neutralization of toxic substances. Some chemical factories and biopharmaceutical factories use sodium bicarbonate as deodorant. In the anaerobic process of wastewater, baking soda can act as a buffer to make the treatment easy to control and avoid causing methane. In the treatment of drinking water and swimming pools, sodium bicarbonate plays an important role in the removal of lead and copper and the regulation of pH and alkalinity. In these industrial sectors, sodium bicarbonate is widely used.
