詳細

詳細

Potassium periodate is widely used as an oxidizing agent. It produces singlet oxygen (¹O₂) in alkaline medium via a non-photochemical pathway. This singlet oxygen can selectively oxidizes aqueous organic pollutants.

アプリケーション

Potassium periodate may be employed as a chromogenic reagent for the sensitive estimation of phenothiazine drugs (either in pure form or in pharmaceutical formulations). It may also be used in the following:

• To compose silica-based slurries for polishing of ruthenium surface.
• To prepare slurry containing glycine for ruthenium and copper polishing.
• Spectrophotometric estimation of manganese in soil and fertilizer samples.4
