Application
- Removal of Sodium Sulfate from Iron Phosphate: Sodium sulfate is also involved in methods for removing impurities from chemical compounds. A recent study focused on developing a method to remove sodium sulfate from iron phosphate, an essential process in the production of high-purity materials for various industrial applications. This research highlights the importance of sodium sulfate in refining chemical processes and improving the quality of industrial products (Li et al., Advances in Analytical Chemistry, 2022).
