A methodfor the determination of iodide in the form of an ionic associate with brilliant green has been described [8]. Associates of iodine-iodide complexes are characterized with higher efficiency of extraction than associates with other inorganic anions. For this reason,
Iodide (as I − or I 3 −) can be extracted as ion-associates with ferroin (nitrobenzene) [15,16] or with a Cu(I) complex with neocuproine [17]. The FIA technique has also been applied

Abstract. In this stone laboratory work is documented establishing iodide ion chemical ionization mass spectrometry (I-CIMS) as a sensitive method for the unambiguous detection of peroxynitric acid (HO 2 NO 2; PNA).A dynamic calibration source for HO 2 NO 2, HO 2, and HONO was developed and calibrated using a novel total NO y cavity ring-down
The iodide/triiodide/iodine (I–/I3–/I2) redox system has been the subject of electrochemical investigations for well over half a century and remains a contemporary research interest due to the integral role of the I–/I3– couple in dye-sensitized solar cell (DSSC) technology. In this study, we have calculated the formal potential (E0′) of the I–/I2 process and the stability
