Introduction to Sodium Persulfate Drying

Sodium persulfate (Na₂S₂O₈), a strong oxidizing agent and inorganic salt, is widely used in polymer initiation, printed circuit board (PCB) etching, environmental remediation, and textile bleaching. Drying is a critical step in its production to remove moisture, enhance stability, and ensure consistent reactivity in industrial applications. Proper drying prevents decomposition, caking, and loss of oxidizing efficiency, which are vital for safe storage and performance.

Drying Process Overview
Sodium persulfate’s sensitivity to heat, moisture, and contamination requires controlled drying conditions. Common methods include:Hot boiling drying

Hot boiling drying
The granular solid material is added to the fluidized bed dryer by the feeder, the filtered clean air is heated and sent to the bottom of the fluidized bed by the blower, and contacts the solid material through the distribution plate, to form fluidization to achieve air-solid heat and mass exchange. After the material is dried, it is discharged from the discharge port, and the exhaust gas is discharged from the top of the fluidized bed, and the solid powder is recovered by the cyclone dust collector and bag dust collector before being emptied.
