摘　　要：分别利用气相分子吸收光谱法和分光光度法测定麋鹿栖息地水体中的氨氮含量,并对两种方法的分析性能及实际样品测定值进行了综合比较。结果显示,两种方法对实际样品测定值的相对偏差小于5%。两种方法的准确度与精密度相差不大,但采用分光光度法分析麋鹿栖息地水体中氨氮分析时间长,使用气相分子吸收光谱法显著提升了分析效率。气相分子吸收光谱法可以较好地应用于麋鹿栖息地水体中的氨氮的快速分析。The content of ammonia nitrogen in water of elk habitat was determined by gas-phase molecular absorption spectrometry and spectrophotometry respectively,and the analytic performances as well as the results based on the two methods were compared comprehensively.The relative deviation of the two methods was below 5%and the accuracy and precision were similar,but the analytic efficiency was greatly improved by the gas-phase molecular absorption spectrometry method,which can be well applied in the rapid determination of ammonia nitrogen in water of elk habitat.
