Abstract:

A set of online automatic monitor of total nitrogen(TN)and total phosphorus(TP)for water quality hasbeen developed based on the determination by ultraviolet ozone synergistic oxidative digestion-ultraviolet and visi-ble spectrophotometry. According to experiments，some influencing factors of the instrument in every segment of themonitoring process are analyzed，and the design scheme and operating parameters of the instrument are optimized soas to further improve the determination accuracy of total nitrogen(TN)and total phosphorus(TP)

Key words: total nitrogen, total phosphorus, monitor, ultraviolet and visible spectrophotometry
