Application of a. Strip Ion-Selective Electrode Sensor for Hydroponic Nutrient Solution Analysis - NO3 Analysis -

  • 초록

    A simple disposable thick-film potentiometric strip has been developed and evaluated for hydroponics application. The strip consisted of low ion-selective electrodes (ISE) fabricated by screen-printing technology. The electrochemical responses of ion sensors for nitrate, ammonium, potassium, and magnesium were measured with specially designed 16-channel low voltage signal transducers. The analytical characteristics of the sensors were comparable with those of conventional ISE sensors. The thick-film sensors exhibit linear relationships over five concentration decades. The concentration of N $O_3$ - ion in standard solution can be determined by direct potentiometric measurements without any conditioning before measurements. However, measurement of $K^{+}$ , N $H_4$ $^{+}$ , and $Mg^{2+}$ ionic concentrations in nutrient solutions seems not feasible.
