摘要
主要研究了离子色谱法对电子束脱硫脱硝副产物中阴离子的分析方法。采用AS1 4分离柱 ,用Na2 CO3 /NaHCO3 淋洗 ,流速为 1 .2mL/min,成功测定了脱硫脱硝副产物中Cl-,NO-3 ,SO2 -4的含量。各阴离子在检测条件下有很好的线性 ,样品测定的整个过程可在 1 3min内完成 ,回收率在 95 %～ 1 0 7%之间。并与经典的氯化钡沉淀法测定含硫量数据进行了比较 ,测定结果满意。该方法的建立 ,为脱硫脱硝副产物作为肥料使用提供快速。
Ion chromatographic procedure was described for the determination of anions in by products of irradiation of flue gas with electron beam. Separation was performed with Na 2CO 3/NaHCO 3 as mobile phase at a flow rate of 1.2mL/min. The separation of the seven impurities was accomplished with a Dionex IonPac As14 column. The analysis was completed in 13 min.Good results were achieved for determination of Cl -,NO - 3,SO 2- 4. The method was characterized by rapidity, sensitivity and simultaneous determination of several kinds of ions.
