摘要：
Quantification of impurities in ionic liquids is a crucial task in assessing the reliability of physical constants and solvent properties: taking into account the particularities of the ionic matrix, a simple routine method using capillary electrophoresis (CE) is developed to determine the halide content at the ppm level in water-immiscible ionic liquids.
