Abstract
The equilibrium and dynamic surface tensions of sodium N-coconut oil acyl amino acids,which were synthesized using waste silk as raw material,were measured by wilhelmy plate method.At the same time,both the critical micelle concentrations（cmc）and standard thermodynamical functions such asΔGθm,ΔHθmandΔSθm at temperatures of 30 ℃,35 ℃,40 ℃,45 ℃ were calculated respectively.The results showed that the process is driven byΔSθm.The equation of CMC-T was obtained.Average value of the ion binding constant between micelle and reverse ions K0 is 0.874 3.Meanwhile,the effects of temperature and concentration on diffusion constant Da and Ea were studied and adsorption process model was discussed.关键词
