Abstract
The influence of different electrolytes on the absorption of sodium dodecylbenzene sulfonate and dodecylpyridinium chloride in acetate fibers has been investigated. The electrolytes studied were LiCl, NaCl, KCl, RbCl, CsCl, NaBr, NaNO 3, and NaClO 4. The extent of sodium dodecylbenzene sulfonate absorption increased markedly with increasing size of the alkali metal cations, that is, in the order Li + < Na + < K + < Rb + < Cs +. The anions were found to have no differential effect. The extent of dodecylpyridinium chloride absorption increased with increasing size of the anions, that is, in the order Cl − < Br − < NO 3 − < ClO 4 −, and increased slightly with decreasing size of the alkali metal cations, that is, in the order Cs + < Rb + < K + < Na + < Li +. The equilibrium absorption data of the surfactants were analyzed on the basis of a general theoretical model, and the influence of electrolyte ion on the extent of surfactant absorption was discussed in terms of the interaction between surfactant ion and electrolyte ion.
