Abstract:
A new stick type sensor is fabricated to analyze the quality of drinking water. The sensor is a fractional order impedance, which shows constant phase behavior over a wide frequency range (200 kHz to 1 MHz) in drinking water. The parameters of the sensor such as the constant phase angle (θ) and the fractional exponent (α ≤ 1) vary with the change in the ionic impurities of water. Fabrication of the sensor is easy, requires cheap materials, and is bulk producible at low cost. For 600 ppm change in the total dissolved solids value of the water sample, there is nearly an 18° shift in the phase angle of the fabricated sensor. The sensor can be utilized to make a prototype probe and preliminary experimental work is carried out to explore the effectiveness of the sensor to measure the quality of drinking water.
