ملخص: Both HUO2PO4[middle dot]4H2o (HUP) and PVA-H3PO4 are proton-conducting electrolytes presenting high conductivity in the low to medium range of temperatures. Mixed with compounds able to exchange protons, such as [gamma]-MnO2, [alpha]- and [beta]-PbO2, composite materials have been obtained and used as inner references of all-solid glass electrodes. The sensors prepared in this work exhibit Nernstian responses and the potentials of the electrodes versus the external pH obey to the relation E = A(T)-(2.3RT/zF)pHe. The slope dE/dpH obtained at 25 [deg]C and the response times of the different sensors tested in this investigation are comparable to those of a commercial TB/HS glass electrode.
