摘　　要：采用抗坏血酸和铁粉化学还原法对水中亚氯酸根（Cl O2-）进行了去除实验研究。结果表明,抗坏血酸静态还原法去除Cl O2-在抗坏血酸与Cl O2-的质量比为6.24,p H=5.5,反应时间为30 min时去除率为100%。铁粉动态还原法去除Cl O2-在p H=6.0时,2.0 g铁粉处理900 m L浓度为3.37~27 mg/L的模拟Cl O2-水样,出水中Cl O2-浓度为0.337 mg/L,去除率达到96.3%,且出水总铁和Cl O2-都能达到《生活饮用水卫生标准》（GB 5749-2006）。Vitamin C and iron powder removal of chlorite by chemical reduction methods were studied. Experimental results showed that under the mass ratio of vitamin C and C1O2- 6.24, pH 5.5, adsorption time about 30 minutes, the removal rate can be up to 100%. And using 2.0 g iron powder for 900ml chlorite water samples with concentrations of 3.37-27 mg/L and pH 6.0, the adsorption rate of chlorite can be up to 96.3%, with effluent concentration of chlorite up to 0.337 mg/L, which can meet the standard of GB 5749-2006 of Sanitary Standard for Drinking Water.
