Iodide sources in the aquatic environment and its fate during oxidative water treatment - A critical review

Urs von Gunten

Iodine is a naturally-occurring halogen in natural waters generally present in concentrations between 0.5 and 100 mu g L-1. During oxidative drinking water treatment, iodine-containing disinfection by-products (I-DBPs) can be formed. The formation of I-DBP ...
