a Sensing characteristics of the proposed sensor operated in CV mode with a voltage sweep rate of 100 mV/s. Insets are the dependence of the response signal on NaClO concentration. b Influence of the scan rate on the response signal of the proposed sensor. c Schematic diagram of the experimental flow injection device. d Sensing behavior of the fabricated sensor operated with the amperometric method. Insets are the dependence of the response signal on the free chlorine concentration
