Sodium Periodate Storage — NaIO4 Specialty Oxidant Tank Selection

Storing Sodium Periodate? Start Here

Sodium periodate is a specialized chemical used in analytical chemistry and pharmaceutical synthesis, known for its role in breaking down certain sugar structures and mild oxidation processes. It's a white crystalline solid that dissolves in water, and its solutions are stable if kept in the dark. If you're dealing with sodium periodate, it's crucial to store it properly to maintain its effectiveness and ensure safety.

Can you store it in a poly tank?

Yes, sodium periodate can be stored in polyethylene (HDPE or XLPE) tanks. These materials are suitable for most concentrations used in labs and pilot plants. For high-purity applications, polypropylene or stainless steel may be preferred.

Key Issue: Light Sensitivity

Sodium periodate solutions are sensitive to light, which can cause them to decompose. To prevent this, use opaque tanks or store the solutions in areas with low UV lighting if they need to be kept for more than a day or two.

The safety that actually matters

• Store in a cool, dark place to prevent decomposition.
• Use appropriate personal protective equipment (PPE) when handling to avoid skin and eye contact.
• Ensure good ventilation to avoid inhalation of any fumes.

Common questions

Can sodium periodate cause fires?

Yes, it is a strong oxidizer and can intensify fires, so keep it away from flammable materials.

What materials should I avoid when storing sodium periodate?

Avoid using carbon steel, aluminum, copper, and brass, as they can react with sodium periodate.

What type of gaskets should I use?

EPDM is generally preferred, but for pharmaceutical applications, Viton (FKM) might be a better choice. Always check with the manufacturer’s compatibility chart.
