Studies on bipolar membranes Part III: conversion of sodium phosphate to phosphoric acid and sodium hydroxide

摘要

The electrodilytic water dissociation process employing bipolar membranes has been used successfully for obtaining acids and alklies from salts. Earlier reports by us described the preparation of bipolar membranes and their applications in converting sodium sulphate into sulphuric acid and sodium hydroxide; sodium acetate into acid and soidium hydroxide [G.S. Trivedi et al., React. Funct. polym. 28 (1996) 243; Ibid: 32 (1997) 209]. In this paper as an extension of our earlier published works the experimental results on the conversion of sodium phosphate to phosphoric acid and soidum hydroxide under different expermental conditions are described.
