Product Application
Polymerization Initiator
Ammonium persulfate generates SO₄⁻· free radicals through thermal decomposition, which efficiently initiates the chain polymerization of vinyl monomers. It is the core initiator for emulsion polymerization and water-soluble polymer synthesis. Its advantages are environmental protection, economy and pH/temperature adaptability, but the dosage must be precisely controlled (0.01%–1%) to avoid side reactions.
Wastewater Treatment
Polyvinyl alcohol can adsorb pollutants and purify water in the field of wastewater treatment.
Industrial Bleaching and Decolorization
Sodium persulfate has become an efficient choice for industrial bleaching and decolorization due to its strong oxidizing properties and controllable reaction conditions, especially suitable for the fields of textile, papermaking and water treatment. Its effect depends on the degradation of pigments by active oxygen free radicals, and the effect is regulated by pH, temperature and concentration.
Soil Remediation
Sodium persulfate has become the core oxidant for soil remediation due to its strong free radical oxidation, adaptability to multiple pollutants and flexible activation methods. It is highly efficient (rapidly degrading more than 90% of organic pollutants and converting heavy metal forms), environmentally friendly (non-toxic degradation products and synergistic microbial remediation) and technologically extended (electric power assists in solving the problem of clay diffusion).
