Abstract:

Analysis and determination of a mixture of halides (F-, Cl-, Br- and I-) and oxyhalides (ClO3- and BrO3-) have been realized by ion exchange chromatography (IEC) with UV-indirect detection mode (IEC-IPD). We have used a stationary phase Metrosep Anion Dual1 Metrohm (150 x 3 mm D.I.), polymeric phase constituted by hydroxyethyle methyacrylate with mobile phase formed by aqueous solution of ortho-phtalic acid as ion developer. In this case, profile separation was presented by effects study; concentration of ortho-phtalique and mobile phase pH. We have also realized the separation of both couples (BrO3-/Br-) and (ClO3-/Cl-). Chromatographic system developed is stable, no perturbation of base line and no interferences of analyzed anions have been occurred.

Keywords:

halides, oxyhalides, ion exchange chromatography, UV-indirect.
