Description

General description

Perchloric acid (HClO₄), an oxygen acid of chlorine, is strongly acidic in nature. Hydrates of perchloric acid are obtained on its dissolution in water.

Application

Perchloric acid has been used to deactivate chloramine-T during the spectrophotometric determination of collagen content of the rat tibialis anterior (TA) tendons and tendon constructs.

It also may be used in the following studies:

• Determination of reduced glutathione (GSH) and oxidized glutathione (GSSG) content in liver tissues by high performance liquid chromatography (HPLC).
• As an oxidizing agent in the estimation of sulfur (S) in plant samples.
• As a solvent for the dissolution of plutonium.
