General description

Sodium perchlorate monohydrate (NaClO4· H2O) is a hydrated sodium salt. Its crystals were reported to exhibit a monoclinic crystal system having space group C2/c. It is a strong oxidizer.

Application

Sodium perchlorate monohydrate can be:
  • Used as a supporting electrolyte in the preparation of polypyrrole (PPy) film.
  • Doped with host polymer NaCMC (sodium carboxymethyl cellulose) to prepare electrolyte film (NaCMC-NaClO4 H2O) which is used in the electrochemical cell.
  • Used as an oxidizing agent to remove color from the textiles waste water.
