摘要：
This paper shows how a porous graphitized stationary (PGC) phase can be modified to work in RP-HPLC ion-interaction reagent (IIR) mode. Aqueous solutions of alkylammonium o-phosphate salts are used as IIRs and the analytes are the inorganic anions, iodide, iodate, bromide, bromate, nitrite, and nitrate. Comparisons with the results obtained under the same conditions for an ODS stationary phase show that the use of the PGC column permits extension, to IIR chromatography, in the pH range of only acidic values.
