Ion-Selective Polymeric Membranes for Chemical Sensors. I

摘要

The aim of this work was to develop cation-sensors of clinical interest, i.e. potassium, calcium, magnesium sensors. Initially, new PVC based selective membranes were obtained. The potassium sensor using benzo- 18-crown 6 shows a slope of 57.51 mV.dec~(-1), while the calcium sensor using ETH 129 presents a slope of 29.11 mV.dec~(-1) and the magnesium sensor using benzo-15-crown-5 has a slope of 27.77 mV.dec~(-1).
