Abstract

The processes of adsorption of iodine and the organic dye, Rhodamine C from their aqueous solutions by glassy PET (polyethylene terephthalate) samples strained in an absorption active medium have been studied, up to various degrees of elongation. It was found that these samples are able to absorb a significant quantity of iodine but Rhodamine C is not adsorbed at all. This effect is explained by the ability of the structural elements of the craze to undergo a type of Brownian movement and to peptization due to the action of the adsorption-active medium.
