Impurities in sulfuric acid
Sulfuric acid is the most-produced chemical in the world. In fact, it is so important that, together with chlorine, it is sometimes used as an indicator of a country’s economic development. Historically named oil of vitriol, it has been known for a long time.
A large portion of the sulfuric acid produced is used in agriculture as a fertilizer. However, the list of uses for sulfuric acid is very extensive, including but by no means limited to:
- The production of cleaning agents
- Battery production (as an electrolyte)
- The pharmaceutical industry
- The chemical industry
- The production of resins, paints, inks, dyes, and polymers
For most of these applications, the sulfuric acid must be of sufficient purity. Metrohm offers a series of techniques and applications to determine impurities. Read more below.
