摘　　要：对使用连续流动分析仪分析氨氮在石油化工行业中存在的典型干扰因素进行了研究。通过对典型还原性盐、有机胺类、醛醇类有机物、钙金属离子及余氯等因素进行干扰实验,确认在较高浓度的还原性物质、钙金属离子及余氯等存在条件下,氨氮测定存在明显干扰,需要进行相应前处理后方可测定。The typical interference factors of ammonia nitrogen in petrochemical industry are studied by using continuous flow analyzer.Through interference experiments on typical reducing salts,organic amines,aldehydes and alcohols,calcium metal ions and residual chlorine,it is confirmed that there is obvious interference in the determination of ammonia nitrogen in the presence of high concentrations of reducing substances,calcium metal ions and residual chlorine,and it is necessary to carry out corresponding pretreatment before determination.
