Sažetak
Miniaturized solid-state electrodes fabricated by inkjet printing provide innovative application scenarios of potentiometric sensing [1]. We present here the development of a reference paste that – when used on a printed electrical contact – gives a reference electrode. Such a paste was prepared by an innovative intense pulsed light (IPL) photoreduction of a 10% polyvinyl butyral (PVB) in a methanol solution of AgNO3 and NaCl, yielding a silver/silver chloride reference paste (RM). Firstly, the RM was drop cast on a glassy carbon disk electrode (RM-GC) [2]. The potentiometric response of the electrode in aqueous solutions of KCl, NaNO3, NaCl, and CaCl2 of different concentrations versus commercial reference electrode, as well as the response of the electrode to pH changes, was examined. A stable electrode potential was achieved by optimizing: IPL photoreduction parameters, volumes of the RM, and conditioning time. Lastly, the optimized reference membrane was transferred onto a planar inkjet printed silver electrode and characterized correspondingly.
