电导法氨氮自动连续监测仪的设计与研究

Design and Study on Conductometry Ammonia On-line and Continuous Monitoring Detector

介绍一种可在线自动连续测定水体中氨氮的监测仪,该仪器以吸氨试剂电导率与氨氮质量浓度的关系为依据,运用流通式管路设计,可实现氨氮质量浓度与氨氮总量的自动连续监测。经验证,仪器的各项性能指标均能满足《氨氮水质自动监测仪技术要求》(HJ/T101-2003)。

A kind of on-line and automatic monitoring detector is introduced,which is based on the correlation of conductivity and ammonia massconcentration.A type of flowing-through monitor has been designed to detect the concentration and total discharge of ammonia in the water automatically and continuously.Test results prove that technological performance indexes are very good and can satisfy the ＂The technical requirement for water quality automatic analyzer of ammonia＂（HJ/T 101-2003）.
