Review of Chloride Ion Detection Technology in Water

Dan Wu, Yinglu Hu, Ying Liu, Runyu Zhang
2021 Applied Sciences  
The chloride ion (Cl−) is a type of anion which is commonly found in the environment and has important physiological functions and industrial uses.  ...  However, a high content of Cl− in water will do harm to the ecological environment, human health and industrial production. It is of great significance to strictly monitor the Cl− content in water.  ...  Acknowledgments: The authors thank the Teaching Reform Project of Zhejiang University for the research funding. We would also like to thank Li Yang for experimental technology consultation.  ...

A portable battery-powered flow injection monitor for the in situ analysis of nitrate in natural waters

N. J. Blundell, A. Hopkins, P. J. Worsfold, H. Casey
1993 Journal of Automatic Chemistry  
The monitor uses the cadmium reduction/diazotization method to analyse for nitrate with a linear range of 0 to 12 mg l-1and a limit of detection of 0.05 mg l-1(NO3-N).  ...  The system is controlled by an in-house microcomputer system that enables the monitor (including a solid state detector) to operate from a 12 V battery supply.  ...  A limited number of chemical parameters (for example ammonia and nitrate) can also be measured, using ion selective electrodes, but such devices can often suffer from electrode fouling and require frequent  ...
