Beschreibung

Allgemeine Beschreibung

Ammonium cerium(IV) sulfate dihydrate (tetraammonium cerium(IV) sulphate dihydrate) is commonly employed as starting material for various organic syntheses. It is widely employed as oxidizing agent. Its thermal decomposition and thermal characteristics have been reported.[1]

Anwendung

Ammonium cerium(IV) sulfate may be used for the determination of urinary iodine by ammonium persulfate digestion on microplate (APDM) method[2] and colorimetric method.[3]

Ammonium cerium(IV) sulfate was used in thin-layer chromatography for the detection of anti-depreβant drugs in human blood and urine samples. [4]
