摘　　要：在水污染评估中,测定水质总磷是至关重要的指标之一。随着工农业的发展和污水排放量的增加,总磷已成为长江流域首要污染物。国家生态环境保护部高度重视总磷监测,监测部门任务量日益繁重,传统钼酸铵分光光度法监测总磷耗时长、效率低,不足以满足高频次、大批量总磷分析,因而总磷自动分析仪应用越来越广泛。通过传统手工方法与IL500总磷自动分析仪分析法比对,结果表明,悬浮物多、颗粒物大的水样需要用传统手工方法进行分析,常规河流、湖库、污水总磷监测可以采用总磷自动分析仪进行批量分析,且方便、快捷、准确、高效。In water pollution assessment,measuring total phosphorus in water quality is one of the crucial indicators.With the development of industry and agriculture、sewage discharge,total phosphorus have become the primary pollutants in the Yangtze River Basin.The Ministry of Ecology and Environmental Protection of the People's Republic of China attaches great importance to total phosphorus monitoring,and the task of monitoring departments is becoming increasingly heavy,the traditional ammonium molybdate spectrophotometric method for monitoring total phosphorus is time-consuming,inefficient,and insufficient to meet the requirements of high-frequency and large-scale total phosphorus analysis.The application of automatic total phosphorus analyzers is becoming increasingly widespread.By comparing the traditional manual method with the IL500 total phosphorus automatic analyzer analysis method,water samples with high suspended solids and large particles need to be analyzed using traditional manual methods.Conventional monitoring of total phosphorus in rivers,lakes,and reservoirs,as well as sewage,can be conducted in batches using total phosphorus automatic analyzers,which is convenient,fast,accurate,and efficient.
