如果Cl02在饮用水处理中仍然是一种可行的替代品，那么将二氧化氯处理后的饮用水中的无机副产物亚氯酸盐离子和氯酸盐离子降至最低是很重要的。描述了使用二氧化硫亚硫酸盐离子化学将亚氯酸盐离子定量去除至低于0.1 mg/L水平，以及使用游离氯去除二氧化硫亚硫酸盐离子。pH值为5.5至8时，描述了化学计量比和速率定律。 5，以便该化学物质可以直接应用于现有的饮用水处理设施。包括32个参考文献、表格和图表。

Minimizing the inorganic by-products chlorite ion and chlorate ion in drinking water treated with chlorine dioxide is important if Cl02 is to remain a viable alternative in potable water treatment. The use of sulfur dioxide-sulfite ion chemistry to quantitatively remove chlorite ion to below the 0.1-mg/L level is described, along with the use of free chlorine to remove the sulfur dioxide-sulfite ion. The stoichiometry and the rate law are described for pH values of 5.5 to 8.5 so that the chemistry can be applied directly in existing drinking water treatment facilities. Includes 32 references, tables, figure.
