摘　　要：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1.35mmol/L的Na2CO3与1.0mmol/L的NaHCO3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。The anion chromatography conductance method and electrochemical automatic regeneration suppressor were used,1.35 mmol/L Na 2 CO3 and 1.0 mmol/L NaHCO3 mixture were chosen as the eluent,to make analytical determination to the anion in steam water of refinery.The recovery rate is 98%～104% and RSD is less than 5%.This method is accurate and rapid,and can be extensively used in actual production.
