Abstract
Using the radio-tracer technique the dynamic behaviour of a14C-octadecanoicacid monolayer spread on a gelatin adsorption layer was investigated. The experimental set-up and conditions are given.
It was shown that the dynamic behaviour significantly differs form that of a14C-octadecanoic-acid monolayer spread on a 10−2 M/dm3 HCl solution.
The differences were explained on the basis of the ionic interactions of the octadecanoic acid monolayer with the gelatin. The aimed blocking of the ionic groups of the gelatin by means of an anionic (SDS) and a cationic (CTAB) surfactant lead to the result that the dynamic behaviour of the spread monolayer did not differ from that spread on a gelatin-free aqueous solution. So the addition of SDS and CTAB to the gelatin solution dependent upon the concentration used, leads to mixed surfactant/gelatin complexes or to the formation of a multilayer system consisting on an octadecanoic monolayer on the top of a gelatin-surfactant complex adsorption layer.
The restriction of the interaction between the spread monolayer and the gelatin by both surfactants could be explained as the result of a sterical hindrance.
