氯胺可能会干扰游离有效氯（FAC）测试。讨论了一氯胺、二氯胺和三氯化氮对三种不同方法分析FAC的影响。详细讨论了FACTS、DPD比色法和DPD Steadifac三种测试方法以及所用的实验程序。包括16个参考文献、表格和图表。

Chloramines may interfere with tests for free available chlorine (FAC). Discussed are the effects of monochloramine, dichloramine, and nitrogen trichloride on the analysis of FAC by three different methods. The three test methods, FACTS, DPD-colorimetric, and DPD-Steadifac, are discussed in detail along with the experimental procedures used. Includes 16 references, tables, figures.
