• 中文摘要： 本文對批式吸附系統提出一數學模式,探討在非線性吸附等溫線下,吸附控制步驟包含液膜擴散及粒內擴散時之動力學。在攪拌槽中,測定陰離子交換樹脂Ionac AFP 329吸附水溶液中酚之速率,結果顯示粒內擴散係數隨溶液初濃度及溫度之增加而增加,但隨樹脂粒徑之增加而稍為減小,又液膜中之質傳係數可用下式表之:Sh=2+0.0215(d/sub p//sup (4/3)/.epsilon./sup (1/3)//V)/sup 1.10/ S/sub c//sup (1/3)/(C/sub o//C/sub ref/)/sup 0.486/或Sh=2+0.000122Rep S/sub c//sup (1/3)/(C/sub o//C/sub ref/)/sup 0.486/式中 3000
• 英文摘要： A mathematical model is proposed to treat the batch adsorption system under a combined external and intraparticle diffusion-controlled kinetics with a nonlinear adsorption isotherm. The adsorption rate of phenol on the anion exchange resins Ionac AFP 329 in a stirred vessel was studied. It was found that the intraparticle diffusion coefficients increase as the initial concentration and temperature increase, and decrease slightly as the particle size increases. The mass transfer coefficient for the external diffusion can be expressed by the proposed correlation: Sh=2+0.0215(d/sub p//sup (4/3)/.epsilon./sup (1/3)//.nu.)/sup 1.10/Sc/sup (1/3)/(C/sub o//C/sub ref/)/sup 0.486/ or Sh=2+0.000122Rep Sc/sup (1/3)/(C/sub o//C/sub ref/)/sup 0.486/ where 3,000
