Sensors nitrite analysis

Phosphorus and nitrogen sensors A very important area where the use of sensors for process analysis has gained much interest is in wastewater monitoring. In particular, the use of analyzers for monitoring of nutrients (nitrate, nitrite, ammonium, and phosphate) and organic matters is of considerable interest. 

Figure 6 Typical Signal Response of P3MT Anion Sensor Towards Sodium Nitrite at Concentrations of 5.5 x 10, 1.1 x 10 , 2.2 x 10" , 5.5 x 10" and 1.1 x 10" M in Flow Injection Analysis Mode...

Environmental detection of toxic compounds harmful to human health, such as dihydroxybenzene, nitrite, nitrobenzene, and nitroaromatics in water, can also be carried out with sol-gel nanocomposite-based sensors. The electrochemical determination of these target analytes on a bare commercial solid electrode produces weak signals at high overpotentials. Taking advantage of the catalytic activity of metal nanoparticles, the sensitive electrochemical analysis of these...
