Sorption of o-Bromobenzoic Acid on the Surface of Dispersed Ice from an Aqueous Solution of KCl
摘要
Abstract
The interaction of o-bromobenzoic acid with the surface of dispersed ice was studied by the method of sorption from solution. It is shown that at low concentrations, sorption is caused by a transition of the acid from solution into the quasi-liquid film on the ice surface. At increased concentrations, sorption abruptly increases due to the thickening of the transition film associated with the melting of the bulk phase of ice bordering the film. This is followed by a slowdown in acid sorption due to the adsorption of acid molecules on the surface of ice particles, which prevents the penetration of hydroxonium ions into the quasi-liquid film.
