| Abstract: | Three anion ion-exchange resins(i. e. D-301-R weak basic,D-296 and 201X7 strong basic respectively) were used for the enrichment of methylphosphonic acids in water. Their degradation products were retained on the resins and eluted with saturated anhydrous HCl/methanol solution, then the eluted solution was methylated with dia-zomethane. Finally, the methylating compounds were identified and quantified by gas chromatography-mass spectrometry (EI mode). It was found that the recovery of methylphosphonic acid in water was over 60% when the macroporous weak alkali anion exchange resin D-301-R was applied in the study. . |
