Abstract The preparation of bipolar membranes from a single sheet of polyolephine by sulphochlorination is described in detail. Rectification experiments between salt solutions and between HCl and NaOH solutions respectively are described. The transference of salt ions relative to each other and relative to the ions of water have been determined. Some analytical data on the concentration of mobile ions in the membranes during current transport are given. The mechanism of rectification is explained and used to clarify the experimental results. Problems concerning conduction in bipolar membranes are enumerated and some experiments are proposed which may assist in solving them.
