In this work, a simple method for the simultaneous determination of trace anions  in hydrogen peroxide with  preconcentration  technique was investigated. A pre-concentration column was used for the enrichment of the low concentration of anions in hydrogen peroxide whilst the hydrogen peroxide matrix could be excluded before the separation process to avoid any destroy on the analytical column, The IC separation was performed on an IonPac AS23 analytical column with isocratic eluent and suppressor conductivity detection. The detection limit ( signal to nois of 3:1) of fluorid, chloride, nitrate and sulfate were 3.0, 5.0, 8.0 and 9.0 �g/L, respectively. High sensitivity, simple operation, low cost and good selectivity are some advantages of the proposed methods.
