摘要：

Conductivity measurements have been made on PVC-DOPP membranes containing dissolved CaI2 in both a wet and a dry condition. The conductivity in both cases is proportional to the CaI2 concentration at low salt concentrations. Transference number measurements have been made using cells of the type Ag\AgI\membrane, CaI2(c1)\membrane, CaI2(C2)\AgI\Ag. These indicate that the mobile species in the membranes are probably CaI+ and I- rather than Ca2+ and I-.
