摘要：

The separation of organic acids with extremely similar ion exchange retention characteristics is achieved using of solvent-compatible ion exchange columns. The required selectivity is obtained through the use of organic modifiers which produce a separation with both ion exchange and reversed-phase characteristics. This novel ion chromatographic approach has been applied to the separation of alkyl methylphosphonate degradation products of chemical warfare agents which have been previously inseparable using conventional ion exchange techniques. The method is suitable for routine environmental analysis of surface waters, groundwaters, and soils.
