Study on the Interaction in Mixed Adsorbed Films at the Water/Air Interface. I. Phenol and Its para-Derivatives

Abstract

This paper presents a method for determination of the parameter β related to the molecular interaction between two surface active compounds in the mixture. The co-adsorption of phenol para-derivatives, which are well known in medicine and pharmacy as commonly used antiseptic drugs, was investigated. The surface properties of p-methylphenol, p-chlorophenol and p-bromophenol, as well as their mixtures, studies on the basis of surface tension measurements, have been related to their pharmacological action.
