Sodium persulfate is widely used as a strong oxidizing agent in various industrial and chemical processes. In the electronics industry, it is employed for etching printed circuit boards, where it helps remove copper and other metals to create precise circuit patterns. It is also utilized in hair bleaching products and cosmetics due to its ability to break down melanin, lightening hair effectively.

In environmental applications, sodium persulfate is used for soil and groundwater remediation. It helps degrade organic contaminants, such as petroleum hydrocarbons and chlorinated compounds, by generating powerful sulfate radicals. Additionally, it serves as a polymer initiator in the production of plastics and resins, facilitating polymerization reactions.

In the cleaning industry, it is a key component in household and industrial cleaning agents, particularly for removing tough stains and disinfecting surfaces. Its strong oxidizing properties make it effective in breaking down organic matter and killing bacteria. Sodium persulfate is also used in the textile industry for bleaching fabrics and in the paper industry for pulp bleaching, ensuring high-quality, brightened end products.
