| Abstract: | An ion chromatographic method
using cerium() postcolumn reaction and cerium() fluorescence detection was employed to
separate the anions of L-ascorbic acid, nitrite, sulfite, oxalate, thiosulfate and iodide in their
mixtures. Some conditions for separating and determining above six species have been
established. Using a 310\+-3 mol/L carbonate eluent, these anions could by separated
completely. The effects of the concentrations of cerium() and sulfuric acid in the postcolumn
reaction solution and the flow rate of the postcolumn reaction solution on the chromatographic
peak-height were also tested. |
