Abstract

After preparing an all-solid-state copper ion selective electrode (Cu²⁺-ISE) based on PEDOT/PSS conversion layer via electrodeposition, this paper characterizes the morphology and cyclic voltammetry performance of the PEDOT/PSS film, optimizes the deposition time of the PEDOT/PSS film, and tests the reproducibility, selectivity and acid-base resistance of the all-solid-state copper ion selective electrode. The experimental results show that the prepared all-solid-state copper ion selective electrode has a linear response in the range of 1×10^-6 mol·L^-1~1×10^-2 mol·L^-1, with a response time less than 30s, and the response slope of 27.8 mV/ decade. The all-solid-state copper ion selective electrode mentioned above can meet the detection standard of national II surface water.
