the adsorption process followed the pseudo-second order model and intraparticle diffusion and boundary diffusion control the adsorption together.
动力学实验表明,吸附反应遵循準二级动力学模型,且粒内扩散和边界层扩散共同控制吸附过程。
ultrasound can effectively strengthen both the liquid film mass transfer and intraparticle diffusion by which the effect of mass transfer enhancement is obtained.
超声场可有效强化液膜传质、粒内扩散,提高浸取率、加快浸取速率,能达到机械搅拌无法达到强化传质的效果。
the second and third fractions were mesopore and micropore diffusion respectively, and the intraparticle diffusion was the control step.
第二和第三阶段分别是中孔和微孔扩散过程,颗粒内扩散为速率控制步骤。
