摘要
Abstract
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 con-firmed 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.关键词
