标准摘要
[中文适用范围]： 该程序适用于饮用水以及大多数原水和废水的分析。 应用于颜色过深或含盐量过高的水之前，应先进行蒸馏。 使用最大 40 毫升的测试部分，可以测定高达 1 毫克/升的铵氮浓度。 通过采取更小的测试部分可以测定更高的浓度。 [外文原描述]： The procedure is applicable to the analysis of potable water, and most raw and waste waters. Application to excessively coloured or saline waters shall be preceded by distillation. An ammonium nitrogen concentration of up to 1 mg/l, using the maximum test portion of 40 ml, can be determined. Much higher concentrations can be determined by taking smaller test portions.
