废水中氨氮纳氏试剂比色测定方法的改进

Determination of Ammonia Nitrogen in Wastewater With Nessler Reagent Colorimetry

采用改进的纳氏试剂比色法测定废水中的氨氮,以电极法作为参照,与常规纳氏试剂比色法进行了比较。结果表明,用改进的纳氏试剂比色法测定结果的重复性和回收率都很好。

The improved Nessler reagent colorimetric method was used to determine ammonia nitrogen in wastewater. The electrode method was used as the reference, and the improved Nessler reagent colorimetric method was compared with the conventional Nessler reagent colorimetric method. The results showed that the improved Nessler reagent colorimetric method had good repeatability and recovery.
