Resumen:
The evaporation through the air/solution interface of sodium dehydrocholate (NaDHC) aqueous solutions was studied by surface tension and microbalance measurements. The evaporation rate was related to the aggregation processes in the bulk, but not with the adsorption monolayer compactness. Except for very dilute solutions the air/solution interface was saturated by NaDHC molecules, giving rise to a strongly nonideal monolayer. At very low concentration, the adsorbed monolayer behaved as an ideal two-dimensional gas. The results were in agreement with previous research results.
