  • Ion Chromatography and Emerging Contaminants Analysis

    Introduction

       Ion chromatography and emerging contaminants analysis research group is devoted to studying and solving the environmental problem caused by emerging contaminants using advanced chromatographic analysis method and nanotechnology. Based on the chromatography technique and nanomaterials, we try to develop efficient sample pretreatment and chromatography analysis method for emerging contaminants including per- and polyfluoroalkyl substances (PFASs), siloxanes, pharmaceuticals and personal care products (PPCPs), perchlorate, drinking water disinfection by-products, and investigate their occurrence, migration, transformation and fate of in environmental matrixes.

    The current studies include aspects as follows: (1) to develop novel and efficient sample pretreatment and chromatographic analytical method for above-mentioned contaminants in environmental and biological samples; (2) to investigate the environmental occurrence, transport, transformation and fate of emerging environmental pollutants; (3) to establish new ion chromatographic method for the analysis of environment or biology related polar and ionic substances (4) to prepare novel composite nanosized materials and to study their potential application in the field of environment science and analytical chemistry.
