| 中文摘要: |
| 采用亲水性强的AS22型阴离子交换分离柱处理水样，用离子色谱法测定样品中的碘化物，通过优化样品预处理条件、色谱条件，消除常见阴离子干扰，使方法在0 mg/L～5.00 mg/L范围内线性良好。方法检出限为0.002 mg/L，3个质量浓度水平的标准溶液7次测定结果的RSD为0.5%～3.5%，实际水样的加标回收率为85.2%～100%。 |
| 英文摘要: |
| A method for determination of iodide in water by ion chromatography was presented based on IonPac AS22 Column with carbonate as eluent. This paper discussed the sample pretreatment conditions，the optimization of chromatographic conditions, common anionic interference, calibration curve and the detection limit, precision, accuracy, etc.. The results showed that this method was not subject to other anion interference. It had a wide linear range with correlation coefficient R>0.999. The detection limit was 0.002 mg/L, the relative standard deviations of standard solutions at 3 mass concentration levels were in range of 0.5%～3.5%(n=7). Spiked recovery of practical samples were in range of 85.2%～100%. |
