%X The analysis of recycle materials from industrial waste water of sodium hydrosulfite production was made by single-column anion exchange chromatography. The recycle material was sodium formate (HCOONa) in which various anions, such as SO(3)2-, Cl-, thiosulfate, hydroxyethyl sulfonate (HOC2H4SO3-), hydroxyethyl thiosulfate (HOC2H4S2O3-), SO(4)2- and NO3- as impurities were existed simultaneously. Except hydroxyethyl sulfonate anion, all other ions can be separated by using anion exchange column Shim-pack IC-Al (4.6 mm i.d. x 100 mm) with the mixture of 1.8 mmol/L of phthalic acid and 1.35 mmol/L of Tri(hydroxymethyl) aminomethane as eluent. The flow rate of mobile phase is 1.0 mL/min. The injection volume was 20 microL. The column oven temperature was controlled at 40 degrees C. Hydroxyethyl sulfonate anion and SO(3)2- could not be separated at the above conditions, but they did not interfere the determination of HCOO-. The detection limits for HCOO-, SO(3)2-, NO3-, S2O(3)2-, HOC2H4S2O3-, Cl- and SO(4)2- were 1.0, 0.7, 1.4, 5.0, 0.7, 0.2 and 2.0 mg/L, respectively. The recoveries were between 96%-102%, and the relative standard deviations (RSD) were lower than 6.0% (n = 5) for all seven ions. This method is characterized by rapidity, sensitivity and simultaneous determination of several kinds of ions.
