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.
