氧化与还原法除去水体环境中微量亚硝酸盐氮

Study on the Treatment of Trace Nitrite in Aqueous Solution by Redox

探讨了铁屑、Fe2 +、NH+4对亚硝酸盐氮的还原作用以及H2 O2 对亚硝酸盐氮的氧化作用 .结果表明 ,铁屑与H2 O2 对亚硝酸盐氮的处理效果较好 ,紫外光照射有助于H2 O2 对亚硝酸盐氮的分解 .而Fe2 +、NH+4则相对稳定 ,NH+4对亚硝酸盐氮的还原作用受动力学控制 .

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.
