• Abstract: The anion in the steam water of the refinery was analyzed and determined by the ion chromatography conductance method, the electrochemical automatic regeneration suppressor and the mixture of 1.35 mmol / L Na 2 CO 3 and 1.0 mmol / L NaHCO 3 . The recovery was between 98% and 104%, and the relative standard deviation was less than 5%. The analytical method is accurate and fast, and can be widely used in practical production. 采用离子色谱电导法，利用电化学自动再生抑制器，同时选择了 1.35 mmol/L 的 Na 2 CO 3 与 1.0 mmol/L 的 NaHCO 3 混合液作淋洗液，对炼油厂蒸气 水中的阴离子进行了分析测定，回收率在 98% ～ 104% 之间，相对标准偏差小于 5%。该分析测定方法准确、快速，可广泛应用于实际生产中。
