Nitric Acid

HNO₃

1. Overview

What is Nitric Acid?

Nitric Acid is a chemical compound with the formula name HNO3. It is a highly corrosive and strong mineral acid with a variety of industrial applications. It is a colorless liquid when pure, but older samples may appear yellow due to the decomposition into oxides of nitrogen and water. Nitric Acid is a powerful oxidizing agent, making it essential in the manufacturing of fertilizers, explosives, and chemicals. It is also used in the etching of metals and the purification of precious metals such as gold and silver. At Polymaster, we provide specialized storage and handling solutions for nitric acid to ensure safety and efficiency in industrial applications. Nitric Acid is fuming, so all storage needs to be sealed/ scrubbed.

3. Chemical Storage Solutions

Tanks for Nitric Acid Storage

Polymaster’s Self-Bunded range is the ultimate storage solution for nitric acid. This range incorporates the bund with the storage tank, providing a bund capacity of 110% of the internal storage tank. In the unlikely event of a leak, this design prevents chemicals from coming into contact with the environment and personnel. Polymaster’s chemical tanks are not rainwater tanks and follow strict QA processes, such as hydro testing each tank to ensure they are 100% leak-proof.

CDU 110L/220L

Small chemical storage tanks offer advantages over large storage tanks in terms of flexibility, accessibility, and safety. Their smaller size allows for easier handling and transportation, making them ideal for labs, small-scale industrial operations, and fieldwork where mobility is key.

These tanks are suitable for environments with limited space, allowing convenient storage in confined areas. They also facilitate precise inventory management, reducing the risk of overstocking and chemical waste. They can be easily replaced or cleaned, ensuring better hygiene and reducing cross-contamination.

IBC Storage (1,000L)

Intermediate Bulk Containers (IBCs) are versatile and widely used due to their large capacity and convenient design.

Polymaster’s unique Enclosed IBC Bund solves many of the problems associated with IBC storage and chemical/fluid decanting in a weather-resistant, purpose-built enclosure.

Constructed from high-grade polyethylene, the Polymaster Enclosed IBC Bund allows for easy forklift movement of IBCs in/out, with a simple connection made to a 250 litre day tank, eliminating OH&S issues associated with IBC handling.

Bulk (1,500L - 30,000L)

Large chemical storage tanks offer significant benefits over small tanks in terms of efficiency, cost-effectiveness, and operational capacity. These tanks store substantial volumes of chemicals, reducing the need for frequent refilling and minimising downtime in industrial processes. This efficiency translates to lower storage costs and the ability to purchase chemicals in bulk at discounted rates.

Large tanks also centralise storage, simplifying inventory management and logistics while ensuring a continuous supply of necessary chemicals. Fewer large containers reduce the risk of leaks and spills, and these tanks are equipped with advanced safety features to handle hazardous materials securely.

6. FAQ

What is the best way to store Nitric Acid?
  • Nitric Acid is a highly reactive and corrosive chemical that requires special handling and storage. It is important that it is stored within a container that is resistant to corrosive chemicals. This means within a tank or container that is built for the purpose of holding aggressive chemicals. Nitric Acid is fuming by nature, so all storage needs to be sealed and go through a scrubber to remove the toxic fumes from the air. It is very important to store Nitric Acid in a well-ventilated environment due to the toxicity of the vapors. 
Best practices for storing Nitric Acid.

Store Nitric Acid in a cool, dry, and well-ventilated area away from direct sunlight. 

Use containers made of compatible materials, such as our 7080 chemical grade octene 1.5SG to store Nitric Acid. It is important to be sealed with all fumes ventilated through a fume scrubber. 

Store Nitric Acid separately from other chemicals, particularly bases, which can react with it and cause dangerous reactions. 

Ensure that Nitric Acid containers are tightly sealed and labelled with the proper hazard warnings. 

Regularly inspect and check your tank for any signs of damage or wear that may occur and get them repaired immediately. 

What not to store with Nitric Acid.

When it comes to storing Nitric Acid, what you are storing it with is just as important as you can cause serious harm to people on-site or the environment around you. Nitric Acid should not be stored with bases or any other chemicals that can react with it. 

Chemical Storage & Handling

When it comes to the storage and handling of Nitric Acid it is important that it is handled safely, and that everyone on-site is kept safe. Here are a few guidelines to follow to keep your workplace safe: 

Store the chemical in its own designated area, away from other chemicals and direct sunlight. 

With any type of corrosive chemical using the appropriate personal protective equipment (PPE) such as gloves, goggles and face shield is a must, Nitric Acid is no different.  

Avoid inhaling Nitric Acid fumes or mist, which can cause respiratory irritation and other health problems.  

Always handle Nitric Acid with care and avoid splashing or spilling it. 

Do not mix Nitric Acid with any other chemicals or substances without first consulting a qualified professional.
