説明
The adsorption of tetraethylene glycol monododecyl ether, C12E4, has been studied by measuring the electrocapillary curves at the polarized interface between the nitrobenzene solution of 0.1 mol dm−3 tetrapentylammonium tetraphenylborate and the aqueous solution of 0.05 mol dm−3 lithium chloride. C12E4 adsorbed at the interface over the entire polarized potential range of 250 mV. Although C12E4 itself is a neutral molecule, its surface activity was greatly affected by changing the potential drop across the interface; an increase in the potential of the aqueous phase with respect to the potential in the nitrobenzene phase markedly enhanced the adsorption. The complex formation between the adsorbed C12E4 molecules and Li+ ions in the aqueous side of the interface was shown to play a decisive role in determining the dependence of adsorption on the electrical potential difference across the interface. A proposed model for complex formation at the interface based on the Gouy–Chapman double-layer theory well-explained the observed trend in the adsorption Gibbs energy when the potential drop across the interface was changed.
