纳氏试剂光度法测定氨氮影响因素的探讨
摘要：氨氮以游离氨或铵盐形式存在于水中。测定氨氮的方法通常有纳氏比色法、气相分子吸收法、电极法等。纳氏试剂比色法有操作简便、灵敏等特点。本文提出用纳氏试剂光度法测定氨氮的常见问题及解决方法。

Pay reagent luminosity follows the investigation and discussion abstract determining ammonia nitrogen influencing factor: The ammonia nitrogen there exists Yu Shui Zhong in form with free ammonia or ammonium salt. The method determining the ammonia nitrogen has generally pay than color law ， the gas appearance molecule absorb law ， electrode law etc. Mrs.Pay reagent handle characteristics such as simple and convenient ， keen than color law has. The main body of a book is accepted bringing forward use reagent luminosity follows common problem and solution determining the ammonia nitrogen.
