Nitrogen containing compounds are important indicators in water quality monitoring,therefore reliable,accurate,and fast monitoring methods are needed as support.This article uses the continuous flow meter method to monitor nitrite nitrogen,nitrate nitrogen,ammonia nitrogen,and total nitrogen.The results show that the correlation coefficients of the standard curve are all greater than 0.999,and the detection limit,precision,accuracy,spiked recovery rate,and four nitrogen relationship all meet the requirements of the method.The continuous flow analyzer has high sensitivity and accuracy,good stability,and can achieve online sample digestion,continuous detection,simplify sample pre-treatment process.It is more suitable for monitoring water quality of large quantities of nitrogen compounds.
