Improving the response behavior of Cd-selective polymeric membrane electrodes by incorporated lipophilic particles.

Abstract

The influence of incorporated lipophilic particles on the potentiometric response behavior of two Cd(2+)-selective membranes is described. The particles show only minor influence on the selectivity behavior of the membranes. As described earlier for a similar Ca(2+)-selective membrane, the flux of primary ions from the sample to the membrane can be successfully suppressed by the incorporation of lipophilic particles.
