| Abstract: | A study on the determination of Cl~-, NO_3~(-) and SO_4~(2-) in tap water and sea water by reversed phase ion pair HPLC was proposed. The separation of inorganic anions was accomplished on a RP-C_(18) column using ion pair chromatographic technique and the UV detector was used to detected anions at 320 nm by indirect photometric detection method. The mobile phase (pH5.0) composed of 2.0mmol/L tetrabutylammonium hydroxide (ion pair reagent) and 2. 0 mmol/L Salicylic acid (visualization agent)in methanol-water (2: 98). Good separation and determination results were obtained. The detection limit (ng) of anions was as follows: Cl~-, 3.4; NO_3~-, 25.8; SO4_~(2-), 9.6. |
