Descrizione

Applicazioni

• Iron Phosphate Purification: Sodium sulfate is involved in methods for removing impurities from chemical compounds. A recent study focused on developing a technique to remove sodium sulfate from iron phosphate, which is crucial for producing high-purity materials for various industrial applications. This research highlights sodium sulfate′s role in refining chemical processes and improving product quality (Li et al., Advances in Analytical Chemistry, 2022).
