SPECTROPHOTOMETRIC DETERMINATION OF TRACES OF IODIDE BY LIQUID-LIQUID-EXTRACTION OF BRILLIANT GREEN IODIDE-ION PAIR
Iodide in natural waters at the 10(-6) M level is determined spectrophotometrically as the Brilliant Green-iodide ion pair. Iodide is first oxidized to iodine with hydrogen peroxide-sulphuric acid to separate it from other chemical species and extracted into carbon tetrachloride. It is then extracted back into aqueous medium by its reduction with sodium thiosulphate and stabilized as the ion pair with Brilliant Green. At pH 7 the ion pair is extracted into chloroform and the absorbance is measured at 625 nm against chloroform. A linear calibration graph is obtained over the range 5 x 10(-7) – 3.5 x 10(-6) M iodide with a relative standard deviation of 0.38% at the 2 x 10(-6) M iodide level. The apparent molar absorptivity for iodide is 3.0 x 10(5) mol-1 cm-1.
