摘要:

通过测定高浓度氨氮标准品（GSBZ20005—88）的试验,验证了差示分光光度法在测定高浓度样品时的准确度和精密度，说明差示分光光度法在一定情况下能减少多次稀释所带来的误差，可以快速测定高浓度样品。

Abstract:

The differential spectrophotometry experimental is experimented by Standard sample for High Concentration Ammonia Nitrogen ( GSBZ20005—88), Precision test and recovery test indicated the results of test by this method is believable. The method can reduce the error caused by repeated dilution in certain circumstances and can fast determine the high concentration in samples.
