Iodide (as I − or I 3 −) can be extracted as ionassociates with ferroin (nitrobenzene) [15,16] or with a Cu(I) complex with neocuproine [17]. The FIA technique has also been applied for determining iodide: the I − is oxidized with bromine to IO 3 − : the excess of bromine is reduced, the IO 3 − is made to react with added iodide, and the absorbance is measured at 351 nm [ 18 ].

· The interference of Cd 2+ is attributed to form a more stable complex with phen as Cd(phen) 3 2+ and produces an ionassociate with iodide. This interfering ionassociate can be floated similarly at the critical concentrations and more. During the extraction of mercury content, it can also be extracted with dithizone in the same manner .

To a known volume of sample, an excess but known amount of iodide is added, which the oxidizing agent then oxidizes to iodine. Iodine dissolves in the iodidecontaining solution to give triiodide ions, which have a dark brown color.
