标准摘要
[中文适用范围]： 本标准规定了饮用水、原水、地下水、地表水、海水、咸水、工艺水中总有机碳（TOC）、总氮（TNb）和总磷（TP）的多参数方法。 经过化学氧化过程的水、生活和工业废水。 它适用于溶解的和结合的悬浮物质。 该方法可测定 TOC、TN 和 TP。 这些参数的工作范围下限和上限取决于仪器条件（例如样品体积、反应化学物质量），并且可以调整至更宽的范围。 典型的测量范围如图 C.1 至 C.3 所示。 分析程序通过单一氧化过程在仪器上进行。 此方法中的 TNb 测量不包括溶解的氮气。 当样品中存在元素碳、氰酸盐和硫氰酸盐时，TOC 结果中将包含元素碳、氰酸盐和硫氰酸盐。 [外文原描述]： This document specifies a multi‑parameter method for the determination of total organic carbon (TOC), total nitrogen (TN b ) and total phosphorus (TP) in drinking water, raw water, ground water, surface water, sea water, saline water, process water, domestic and industrial wastewater, after a chemical oxidation process. It is applicable to both dissolved and bound suspended materials. The method allows for determination of TOC, TN and TP. The lower and upper working ranges for these parameters are dependent upon instrument conditions (for example sample volume, reaction chemistry amounts) and can be adjusted for a wider range. Typical measurement ranges are shown in Figures C.1 to C.3. The analysis procedure is carried out instrumentally by a single oxidation process. Dissolved nitrogen gas is not included in the TN b measurement in this method. When present in the sample, elemental carbon, cyanate and thiocyanate will be included in the TOC result.
