| Abstract: | Bromide, iodide, bromate, iodate, thiocyanate, nitrite and nitrate can be separated by means of ion-pair chromatography on a reversed-phase column (LiChrosorb RP2), using the tricaprylylmethylammonium ion (Aliquat-336) as counter ion in an acetonitrile-water mobile phase. The elution is monitored with an ultraviolet detector at 205 and 226 nm. The detection limits are in the low nanogram range. |
