Iodate sulfate

Iodate sulfates are mixed anion compounds that contain both iodate and sulfate anions. Iodate sulfates have been investigated as optical second harmonic generators, and for separation of rare earth elements. Related compounds include the iodate selenates and chromate iodates.

Iodate sulfates can be produced from water solutions of iodic acid and sulfate salts.
