| Abstract: | The oxidation reaction of hydrogen peroxide to sodium alizarin sulfonate is catalyzed by micro manganous in sodium hydrogen canbonate medium so sodium alizarin sulfonate fade.The fading velocity is direct ration with manganous content in stitable condition.Therefore the manganous contents are determined by spectrophoto graphy .The method is simple,fast,high,sensitivity and accutrate.It can be used for micro maganous to determine in surface and ground water.The minimum detectabitity is 2μg/L. |

| Keywords: | spectrophoto graphy micro manganous minimum detectability |
