Abstract

Chlorination disinfection is a standard disinfection method for rural drinking water. Low residual chlorine can lead to the proliferation of microorganisms, while high residual chlorine threatens human health. To accurately determine the residual chlorine concentration, this study explores optimizing the inkjet printing process parameters of flexible electrodes to improve electrode impedance performance. Conduct single-factor experiments to assess the control level ranges of six main parameters: post-sintering temperature, printing layers, post-sintering time, inkjet hole spacing, the flexible substrate surface treatment, and printing nozzle count. Response surface analysis (RSM) was employed to obtain optimized parameters, and conduct feasibility verification. The experimental results show that the key influencing factors for preparing flexible electrodes include post-sintering temperature, printing layers, post-sintering time, and inkjet hole spacing, with decreasing influence in that order. The preparation parameters of printing layers, post-sintering temperature, post-sintering time, and inkjet hole spacing are four layers, 127 ℃, 26 min, and 30 µm, respectively. The impedance performance of the printed electrodes is under optimal status, with a resistance of 169.8 Ω and a relative standard deviation of less than 3.0%. The electrochemical behavior of chloride ions on the optimized flexible electrodes was studied, and the results show that the decrease in differential pulse oxidation peak current is linearly related to the logarithm of the chloride ion concentration in the 10^–5 to 10^–2 mol/L range. The verification results validate the flexible electrodes’ feasibility in measuring residual chlorine content in rural drinking water, providing a prospective method for monitoring rural drinking water quality.
