Abstract
Hydrogen $peroxide(H_2O_2)$ reacts with HCr$O^-_4$ in an acidic condition to produce $CrO(O_2)_2$ which exhibits an intense blue color. This reaction is coupled with a technique of Flow Injection Analysis(FIA) for the absorption spectrometry of $H_2O_2$ in the aqueous samples. The method could be applied for the deter-mination of $H_2O_2$ over the range of 2.00{\times}$10^{-6}$M��0.020 M with the limit of detection of ��1.00${\times}10^{-6}$M. The method was also used to successfully determination of the $H_2O_2$ content in the snow and rain samples.
