With the development of social economy and the growth of population,the phosphorus content discharged by industry,agriculture and urban life wastewater gradually increases,resulting in an overall upward trend of total phosphorus content in surface water.This trend is reflected in monitoring data from several countries and regions.As one of the key parameters to evaluate the quality of surface water,the accurate determination of total phosphorus is of great significance to assess the risk of water eutrophication and to develop water environmental protection measures.However,the determination of total phosphorus is challenging due to its various forms and many interfering factors.Therefore,it is particularly urgent to carry out the method research and laboratory quality control for the determination of total phosphorus in surface water.It is necessary to improve the efficiency of sewage treatment and protect the health and stability of the water environment.
