Potentiometric Response Characteristics of Membrane-Based Cs+-Selective Electrodes Containing Ionophore-Functionalized Polymeric Microspheres

Figure 2

Mean potentiometric response curves of PVC-based Cs⁺-selective ISEs containing P-EG and TFPB and plasticized with NPOE (a) or either DOS or FPNPE (b). Mean potentiometric response curves of PVC-NPOE membrane containing TFPB and a mobile Cs⁺ ionophore, either U-EG or CC, are also shown for comparison (c).
