| Abstract: |
| Establish the method for the simultaneous determination of Seven kinds of Anion by ion chromatography. Fluoride, Chlorite, Bromate, Chloride, Nitrite, Chlorate, Sulfate were separated by column IonPac AS-19 with gradient eluent by KOH solution, and were determined by ECD. The correlation coefficients of seven kinds of anion were more than 0.9988, recoveries were 91.6 to 108(%), RSD were 0.13—8.80(%). This method has simple pretreatment, can obtain satisfactory separation and recovery, which is suitable for determination of seven kinds of anion in water. |
