Additional information

Iodine is rapidly hydrolysed and forms several equilibria with different ionic species (I-, OI-, IO3 -, I3 -). Therefore the degradation route of phototransformation of iodine in water is regarded as negligible. However, Miyake and Tsunogai found indications that in marine surface waters photooxidation of iodide ions to iodine occur (Miyake, 1963).
