How to Dispose of Nitric Acid
In this article, we’ll address specifically how to dispose of nitric acid. Like most acids, nitric acid can be neutralized prior to disposal. This chemical reaction greatly reduces the hazardous risks of nitric acid, helping your business to comply with the three tenants of proper waste disposal. The reaction must be completed safely, which we’ll explain in this article.

Proper disposal of chemical reagents is essential for three reasons:
- Legal complianceWorker and environmental safety
- Minimizing business/laboratory expenses
- All labs and businesses working with hazardous chemicals must comply with the regulations set in place by OSHA (Occupational Safety and Health Administration) and local jurisdiction.
These regulations are in place to minimize risks to workers handling hazardous chemicals.Chemical waste disposal can be expensive for labs and businesses. Businesses must schedule waste pick-up from a hazardous waste disposal company. Minimizing your hazardous waste is one way to cut business costs. It will also reduce costs from replacing expired or spilled reagents.
Tetrahydrofuran in Polymer Industry
Tetrahydrofuran (THF) plays a crucial role in the polymer industry, particularly in the processing and production of certain polymers. Here are some key applications of THF in the polymer industry:
• PVC Production: Tetrahydrofuran is an essential component in the manufacturing of polyvinyl chloride (PVC). PVC is a widely used thermoplastic polymer with diverse applications in construction, packaging, automotive, and other industries. THF is used as a solvent to dissolve PVC resin, allowing for the production of flexible or rigid PVC formulations. It helps in the dispersion of additives, plasticizers, and stabilizers within the PVC matrix, facilitating the processing and shaping of PVC products.
• Polyurethane Processing: Tetrahydrofuran is commonly used in the production and processing of polyurethane (PU) polymers. PU is a versatile polymer that finds applications in foams, adhesives, coatings, elastomers, and more. THF is utilized as a solvent in the fabrication of polyurethane films, fibers, and coatings. It helps dissolve the polymer precursors, such as isocyanates and polyols, enabling them to react and form the desired polyurethane structure.
• Polymer Solvent: Tetrahydrofuran is widely employed as a solvent for various polymers, including natural and synthetic polymers. It has excellent solvency for a range of polymers like polyolefins, polyesters, and polystyrenes. THF’s ability to dissolve these polymers makes it useful in polymer characterization, sample preparation, and as a reaction medium in polymer synthesis.
• Polymer Research and Development: Tetrahydrofuran serves as a crucial solvent and reaction medium in polymer research and development. It is used in the synthesis and modification of polymers, allowing researchers to investigate polymer properties, molecular weight control, and copolymerization reactions. THF provides a controlled environment for the synthesis of polymer nanoparticles, block copolymers, and other specialized polymer structures.
• Polymer Recycling: Tetrahydrofuran is employed in the recycling of certain polymers. It can act as a selective solvent to dissolve specific polymers while leaving others unaffected. This property is utilized in the separation and recycling of polymers like polyethylene (PE) and polypropylene (PP), which have similar properties but different solubilities in THF.
Where to restock on nitric acid
Now that you’ve disposed of your expired or degraded nitric acid, you will need to restock with a high-quality replacement from a supplier you trust. Lab Alley offers high quality nitric acid at competitive pricing, with a no-hassle ordering process, and fast delivery.
Conclusion
Chemical waste disposal can be expensive for labs and businesses. Businesses must schedule waste pick-up from a hazardous waste disposal company. Minimizing your hazardous waste is one way to cut business costs. It will also reduce costs from replacing expired or spilled reagents.
