Ion Exchange and Fibre Contraction

Nature volume 164, pages 110–111 (1949)Cite this article

Abstract

IT has been shown1 that birefringent fully swollen calcium alginate fibres of 0·4 mm. diameter contract on replacing the bifunctional calcium ion by the mono-functional sodium ion. Ingersoll and Johnson suggest2, inter alia, that the contraction is due to osmotic de-swelling rather than to devulcanization brought about by ionic exchange1. This explanation is unacceptable for the reasons below.
