| Abstract: | The principle of iodometric and cerous sulfate determination of co ncentration hydrogen peroxide solution were described in the article.The optimu m conditions and the comparison of their results for the two methods' determinat ion were investigated in detail.The results showed that variable coefficient an d relative error of the two methods were very small.They could be used to deter mine hydrogen peroxide.Because the cerous sulfate titration has the advantage o f stabilization of standard solution and without any side reactions,the results obtained by cerous sulfate titration were precise than them obtained by iodomee tric titration. |
