标准摘要
[中文适用范围]: 规定的方法适用于 0.02 至 15 mg/l 范围内的浓度。 表中列出的离子和化合物,如果单独存在或以高于指定极限浓度的组合存在,都会干扰该方法。 由于形成氰醇,醛的存在可能会给出较低的值。 [外文原描述]: The method specified is applicable to concentrations in the range 0,02 to 15 mg/l. The ions and compounds listed in the table, if present single or in combination at concentrations above the specified limiting concentration, interfere with the method. The presence of aldehydes may give lower values because of the formation of cyanohydrin.
