摘　　要：氨和铵中的氮称为氨氮(ammonia nitrogen)。水中氨氮的含量在一定程度上反映了含氮有机物的污染情况。在污水综合排放标准(GB8978-1996)和地表水环境质量标准(GB3838-2002)中,氨氮都是重要的监测指标。为了降低氨气敏电极法测定氨氮时分析故障率,提高数据的准确性和及时性,使日常样品分析工作更快,更准,仪器更稳定运转,员工满意度更高,就氨氮仪器故障因素可能原因进行探究,找出故障频发的原因,针对相关原因进行改善。The nitrogen in ammonia and ammonium is called ammonia nitrogen.The content of ammonia nitrogen in water reflects the pollution of nitrogen-containing organic matter to some extent.Ammonia nitrogen is an important monitoring index in the comprehensive wastewater discharge standard(GB8978-1996)and the surface water environmental quality standard(GB3838-2002).In order to reduce the failure rate of ammonia-nitrogen analysis,improve the accuracy and timeliness of the data,make the routine sample analysis work faster and more accurate,achieve more stable operation of the instrument and higher staff satisfaction,the possible causes of the trouble of ammonia-nitrogen instrument were probed into,the causes of frequent trouble were found out,and the related causes were improved.
