title: Ionic liquid-kaolinite nanohybrid materials for the amperometric detection of trace levels of iodide.
abstract: A nanohybrid kaolinite material with anion exchange properties was obtained by the grafting of an ionic liquid in the interlayer spaces of kaolinite. It was used successfully for the amperometric detection of iodide in aqueous solution and tap water after a pre-concentration step, with a detection limit of 1.5 × 10(-7) M. This electrode has an excellent stability. Its selectivity was tested in the presence of several anions.
