Ammonium Persulfate Storage — Strong Oxidizer Tank Selection
Storing Ammonium Persulfate? Start Here
Ammonium persulfate is a strong oxidizer (PCB etching, polymer initiator, hair bleach). The dissolved solution stores fine in a poly tank. Two things drive the handling: it's an oxidizer (segregate from fuels/organics) and it's a notorious respiratory sensitizer, so dust/aerosol control matters.
Can you store it in a poly tank? Yes.
Persulfate solution (mildly acidic, strongly oxidizing) is compatible with HDPE/XLPE (surface oxidation is cosmetic) with PVC fittings — most metals corrode, so keep it non-metallic. EPDM or Viton gaskets. Use a clean, dedicated, vented tank.
The safety that actually matters
- Respiratory/skin sensitizer — one of the most documented occupational-asthma chemicals. Control dust and aerosols; closed handling.
- Oxidizer — keep away from fuels, organics, and reducers; segregate.
Common questions
- Poly OK for persulfate?
- Yes — HDPE/XLPE with PVC fittings. Keep metal off wetted parts.
- Main hazard?
- It's a sensitizer (asthma) and an oxidizer — control dust/aerosols and segregate from fuels/organics.
