【Abstract】 Trace nitrite removal from aqueous solution was studied by oxidation or deoxidization method. It is shown that H 2O 2 and scrap iron are significant for the removal of trace nitrite, ferrite and ammonium do not have the same effects. The reduction process of ammonium is controlled by dynamics. The oxidation effect of H 2O 2 is promoted by ultraviolet radiation.更多还原
