摘要
阐述应用纳氏试剂比色法测污水中氨氮时,加入纳氏试剂后产生大量灰色沉淀的原因及消除办法,对产生沉淀的机理进行初步探讨。
In determination of ammoniacal/nitrogen in waste water with colorimetry, Nessler reagent was added, a great amount of gray precipitation was generated. This paper analyzed the reasons, presented treating method, and discussed preliminarily on the mechanisms of precipitation.
