Sea water and waters containing bromides and iodides comprise a group for which special procedures are required. The procedure is applicable to concentrations, in terms of chlorine, from 0.0004 to 0.07 mmol/l total chlorine and at higher concentrations by dilution of samples. Interferences of the procedure are noted.
