DETERMINATION OF ANTIMONIC(III) AND ANTIMONIC(V) IN GLASSES BY ION CHROMATOGRAPHY UTILIZING INDUCTIVELY COUPLED PLASMA ATOMIC EMISSION SPECTROMETRIC DETECTION

摘要

Ion chromatography (IC) interfaced with inductively coupled plasma atcmic emission spectrometry (ICP-AES) is applied to the determination of Sb(III) in glass. Total amount of Sb is analyzed by ICP-AES. Thus, Sb(V) is calculated as the difference between Sb(III) and total Sb. The dynamic range of Sb(III) was 0-10 mg/l with the detection limit of 0.5 mg/l. The relative standard deviation was less than 1.5 % in chromatographic peak area. The behavior of Sb in glass can be clearly observed by this technique.
