摘要
本文利用全自动气相分子光谱仪测定水体中的氨氮含量并进行了检出限、精密度和正确度研究试验.试验表明气相分子光谱法测定水体中氨氮,最低检出限、测定下限、精密度、正确度均优于经典的纳氏试剂比色法,满足实际工作需要,可以采用本方法对水环境开展监测工作.
Abstract
In the paper,it utilizes an automatic gas phase molecular spectrometer to measure the ammonia nitrogen in water and conducts tests on detection limits,precision,and accuracy.The results demonstrate that gas phase molecular spectroscopy for determining ammonia nitrogen in water bodies outperforms the classic Nessler's reagent colorimetric method in terms of minimum detection limit,lower limit of quantification,precision,and accuracy.It meets the practical work requirements and can be adopted for environmental monitoring of water.
