General description
Hydrochloric acid is a strong mineral acid. Adsorption of Fe(III) by Dowex-1 anion exchange resin using various concentrations of HCl solutions has been studied.
Application
Hydrochloric acid may be used in the following studies:
- Membrane assisted solvent extraction (MSX) of rare earth elements (such as neodymium, praseodymium, and dysprosium) from NdFeB magnets and industrial scrap magnets.
- Preparation of orcinolhydrochloric acid (Bial′s reagent), which is useful for the quantitative determination of sialic acids.
- Preparation of alcoholic hydrochloric acid-carmine stain.
