Abstract

Binding of N-akylpyridmium chlorides (Clb CI2, and C14) to dodecyl oxyethylene ether (c & and CI2&) micelles is determined in the presence of 5 mol m-3 NaCl at various temperatures by potentiometry which employs an electrode responsive to the surfactants. Binding affinity is expressed in terms of a distribution coefficient, K,, of a cationic surfactant between the aqueous bulk phase and the nonionic micellar phase, and is larger for an alkylpyridinium ...
