Abstract:
From the dynamic surface pressure of Peregal O-20 spreading monolayres, the variation of the model material surface concentrations was obtained by extrapolating method.Taking advantage of the relation Πt～c , the diffusion coefficients (D0) of the Peregal O-20 desorpted from the surface at air-water interface to the aqueous bulk was calculated.The order of D0 was 10-4～10-3 cm2/s.The initial surface concentration is the key factor of influence on the diffusion coefficients of Peregal O-20.
