Subject:
adsorption; aqueous solutions; benzyl alcohol; dioxane; dyeing; dyes; fabrics; gelatin; glucose; inositols; solutes; solvents; spectral analysis; textile fibers; wool
Abstract:
... Relative rates of adsorption by gelatin and by wool have been determined for a number of series of sulfonated azo acid dyes and 2: 1 dye-metal complexes. It is shown that: (i) The rate of adsorption of each dye by a given area of the external surface of gelatin is about four times that by the same area of the external surface of wool; (ii) the logarithm of the rates falls linearly with both the nu ...
