It is used in etching mixtures for zinc and printed circuit boards, and is used for pickling of copper and some other metals.Treatment of metal surfaces (eg in semiconductor manufacturing: cleaning and etching of printed circuits boards). Activation of copper and aluminum surfaces.

Environmental remediation agents: contaminated soil remediation, water treatment (waste water purification); waste gas treatment, oxidative degradation of harmful substances (such as mercury).

Ammonium persulfate is widely used in the storage battery industry because of its good oxidizing and bleaching properties.and Used in the manufacture of persulfate and the purification of ammonium sulfate

Plastics and rubber - Ammonium, potassium, and sodium
persulfates are used as initiators for emulsion polymerization.
Structural materials - Persulfates are used as initiators in
polymeric concrete formulations.
Soil stabilization  - Ammonium persulfate is used as a curing agent in chemical grout systems used to stabilize soil near
dams, tunnels, and buildings.
Inorganic chemicals and minerals - Persulfates are also
initiators for the polymeric coating of graphite filaments.

Desizing agent and bleaching agent-especially for low-temperature bleaching

In enhanced oil recovery, persulfates are used "down hole" for gel forming and breaking. Oil fracturing additives, Drilling Fluid Additives.
