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。
