离子色谱法测定聚合铝铁中的Fe3+、Fe2+
Ion Chromatography for Fe3+/Fe2+ Determination in Polyaluminum Ferric Chloride
【摘要】 采用酸溶解—离子色谱法分析聚合铝铁 (PAFC)中的Fe3+ 和Fe2 + ,具有快速、简便、准确的特点 ,两种价态的离子标准曲线线性关系良好 ,最低检测浓度 :Fe3+ 为 0 .0 18mg/L ,Fe2 + 为 0 .0 2 2mg/L ,样品测试结果令人满意
【Abstract】 An analyzing method of acid decomposition/ ion chromatography used for quantitative analysis of Fe3+/Fe2+ in polyaluminum ferric chloride (PAFC) was proven quick,convenient and accurate.Test result shows that the standard curves of Fe3+ and Fe2+ both have good linear relationship.The minimum detection limits of Fe3+ and Fe2+ are 0.018 mg/L,0.022 mg/L respectively.
