Résumé

High hydrophilic anion stationary phases play a crucial role in the separation behavior of ion chromatography. Herein, we report novel polymeric anion exchangers grafted with polyethylene polyamines, including ethylenediamine, diethylenetriamine, triethylenetetramine and tetraethylene pentaamine, via a facile epoxy-amine polymerization method. The anion exchangers were characterized by scanning electron microscopy, thermogravimetry, Fourier transform infrared spectrometry and elemental analysis. The chromatographic performance of the stationary phases was evaluated with the separation of common inorganic anions, organic weak acids and highly polarizable anions. Seven common anions (F
