摘要：

Adsorption studies have been carried out on seven members of a homologous series of N‐alkyl betaine zwitterionic amphiphiles at the air‐water interface. The standard free energies of adsorption have been calculated and resolved into the separate contributions from the polar head group and the methylene groups in the alkyl chain. These contributions are compared with previously published data for the same compounds undergoing micellization. Copyright © 1969 Wiley‐Liss, Inc., A Wiley Company
