文摘
- •
Dynamic/equilibrium surface tensions of decanoic acid solutions were measured.
- •
Complete sets of ST relaxation curves were obtained using a pendant bubble tensiometer.
- •
The ionic generalized Frumkin model describes the ST relaxation data very well.
- •
A diffusivity of 5.5 × 10−6 cm2/s was determinedfromthe dynamic surface tension data.
- •
Relaxation of the surface/sublayer properties [Γ, ψs, C1s, C1∞, and ψ(r)] was reported.
