At the same time , the intrapartical diffusion and liquid internal mass transfer can been enhanced by ultrasound field , owing to additional stirring , the increasing rate of intraparticle diffusion coefficient is enhanced , while that of the liquid film mass transfer coefficient is reduced under ultrasound field 模型研究表明: freundlich ?兩相阻力模型計算得到濃度與實驗測定值非常吻合,超聲場能有效地強化浸取粒內(nèi)擴散與液膜傳質(zhì),攪拌作用下超聲強化液膜擴散的的能力降低,強化粒內(nèi)擴散的能力增強。
