- Title
Adsorption isotherm of a disperse dye.
- Authors
Romankevich, O.; Red’ko, Ya.
- Abstract
An absorption isotherm equation similar in form to Langmuir’s equation was obtained for monomolecular adsorption of a dye on the inner surface of a fibre for the process of dissolution of a dye in amorphous regions of a fibre using the assumptions concerning formation of dye—macromolecule fragment solvates in the ratio of 1:1. Linearity of the function 1/CF = f(1/CS) is possible both in adsorption of the dye with formation of a monomolecular layer (Langmuir) and in dissolution of the dye in the amorphous part of the fibre-forming polymer with formation of solvates.
