چکیده
A novel paper-based potentiometric platform for the simple and fast monitoring of water hardness is presented. First, ion-selective electrodes calcium magnesium printed on a paper substrate were built optimized. These sensors, which display near-Nernstian sensitivity, used determination concentration these cations calculation hardness. Second, incorporation solid-state reference electrode allowed building an integrated cell artificial real samples (mineral waters). The validation results shows good ability to predict in conventional scale. Truly decentralized measurements demonstrated by integration miniaturized instrument dedicated software portable device. able be performed just under two minutes, including two-point calibration. Since method use cost-effective, it can implemented domestic industrial settings.

This paper describes the design and fabrication of ion-sensing electrochemical paper-based analytical devices (EPADs) in which a miniaturized paper reference electrode is integrated with a small ion-selective paper electrode (ISPE) for potentiometric measurements. Ion-sensing EPADs use printed wax barriers to define electrochemical sample and reference zones. Single-layer EPADs for sensing of c...
متن کاملPotentiometric sensing utilizing paper-based microfluidic sampling.
A new approach to potentiometric sensing utilizing paper-based microfluidic sampling is studied in this work. A solid-contact ion-selective electrode and a solid-contact reference electrode are pressed against a filter paper into which the sample solution is absorbed. The filter paper acts simultaneously as a sampling unit and as a sample container during potentiometric sensing. The paper subst...
