连接基长度对琥珀酸酯磺酸盐型双子表面活性剂水溶液动态表面张力及吸附动力学的影响
Effect of the length of the linker on dynamic surface tension and adsorption kinetics of succinate sulfonate Gemini surfactant in aqueous solution
摘要
Abstract
The dynamic surface tensions of ethanediol bis-secoctyl sulfo succinate (GSS271), 1, 3-propanediol bis-secoctyl sulfo succinate (GSS371) and 1, 4-butanediol bis-secoctyl sulfo succinate (GSS471) aqueous solutions with different concentration were investigated using the maximum bubble pressure method. The process of DST changing with time was described in detail and the influence of connecting group on DST was studied. The n, t*, ti, tmand R1/2of DST were obtained by Rosen model. Meanwhile, the adsorption mechanism was discussed by Ward-Tordai equation. The results showed that the shorter the connection group, the better the dynamic surface activity of GSS surfactant. When c＜cmc, the GSS surfactants were controlled by pure diffusion at the initial stage of adsorption, and were hybrid diffusion-kinetics control at the later stage of adsorption.关键词
