“…Several methods had been introduced for this purpose including colorimetry (Nessler and Berthelot ), titrimetry , potentiometry (ammonia selective electrode) , ion chromatography and photoacoustic spectroscopy . There are some drawbacks to these methods such as using toxic compounds (mercury and phenol) in colorimetric techniques, time‐consuming of titration and the high cost of an ion selective electrode.…”

A new, simple and low‐cost method for patterning hydrophobic barriers in porous support such as paper by Parafilm® has been introduced. This method is then used for electrochemical paper‐based ammonia sensor construction. Ammonia sensor is based on electrochemical concentration cell which ammonia reaction with electrolyte in halves cell caused in concentration gradient and therefore potential difference dependent on ammonia concentration. The effect of concentrations of the involved chemicals, time periods of the required processes, the presence of Faraday cage as well as the effects of different salts used in the salt bridge on the response of the sensor, were investigated in order to find the optimized conditions.
