摘要：This work describes an analytical approach to achieve accurate simultaneousseparation of alkylphosphonic acids (MPA, PPA and BPA) and inorganicanions (chloride, nitrate, sulfate and phosphate) in aqueous media by ionexchange chromatography with evaporative light scattering detector (IECELSD)under isocratic elution mode using Dionex Ion Pac (250 x 4 mm ID)column. Herein, we demonstrate that couples (MPA/PPA) and (MPA/BPA) canbe separated by IEC because a net difference of apparent between these twocouples was noted. The developed chromatographic system offers a successfulmethod to give a good separation of a mixture of MPA, PPA, chloride, nitrate,sulfate and phosphate in aqueous media without baseline derive andinterferences, and with good resolution. It can be applied to the direct analysisof aqueous matrix containing low levels of alkylphosphonic acids and highlevels of inorganic anions (chloride 1000 mg/L, phosphate 1000 mg/L).
