| Abstract: | The elution liquid system of ion chromatogram was studied. The simultaneous detection of polymorph phosphate ion and strong-retention sulfate ion was realized by single column ion chromatography with salt hydrogen phthalate as mobile phase. The detection limit of sulfate ion(SO42)and phosphate ion was 1 ng/mL and 3 ng/mL,respectively.Static and dynamic cation exchange behavior of Y2X8 resin and the possibility of determination of trace sulfur and phosphor in steel by online pre-separation were studied. Further more,sulfur and phosphor in low alloy steel were determined by offline pre-separation-IC and RSD<11%. |
