adsorption barriers

Combined with Word-Tordai equation,the effective diffusion coefficient D_a and the adsorption barrier E_a were obtained.

使用最大气泡法测定了油基十氧乙烯基醚C18H35O(CH2CH2O)10H(Brij97,C18EO10OH),油基二十氧乙烯基醚C18H35O(CH2CH2O)20H(C18EO20OH)水溶液的动态表面张力(DST),考察了结构及温度对DST的影响,详细表征了DST随时间的变化过程,计算了动态表面张力的参数(n,t*,γm),结合Word-Tordai方程计算了表观扩散系数(Da)和吸附势垒(Ea)。

Increase of concentration of the surfactant, decrease of temperature or addition of salts (NaCl) will reduce the apparent diffusion coefficients and raise the adsorption barriers.

结合Word-Tordai方程,计算得到在不同条件下的表观扩散系数Da和吸附势垒Ea。

Combined with Word-Tordai equation, the effective diffusion coefficient D a and the adsorption barrier E a were obtained.

结合Word Tordai方程计算了表观扩散系数 (Da)和吸附势垒 (Ea) ,对其吸附动力学模式进行了研究 ,探讨了DST参数的物理意义 。

However, we cannot obtain information on adsorption barriers directly from the adsorption data.
