Water quality monitoring becomes vital as nations industrialize and centrally plan utilities. This paper examines the sensingcharacteristics of a flexible arrayed chloride sensor combined with an XBee wireless sensing system. The average sensitivity ofthe wireless chloride sensing device was 47.84 mV/pCl and linearity was 0.99. The hysteresis voltages were 50.14 mV and 36.71mV during different solution cycles, with one solution cycle being 1 M→10-1 M→1 M→10-3 M→1 M, and thealternate being 1 M→10-3 M→1 M→10-1 M→1 M. Interference experiments were conducted to obtain selectivitycoefficients for the ClO-on, ClO4-ion, NO3-ion and I-ion for Cl-ion, which were 5.0×10-2, 1.0×10-1, 5.9×10-3 and 5.6×10-1, respectively. Sensing characteristics for real-time wireless measurement were tested using a dynamic microfluidic system.The sensitivity was 60.64 mV/pCl and linearity was 0.98 at 35μL/min. |
