• 中文摘要： 建立一種可同時求得陰離子交換樹脂吸附酚的膜質傳係數及粒內擴散係數的方法,由這個方法求得的膜質傳係數及粒內擴散係數值與利用非線性迴歸數值分析法所得到的值非常一致; 而本方法的主要原理是當.Ybar./Y/sup */小於 0.2時,.Ybar./Y/sup */與時間的關係可表示成.Ybar./Y/sup */=A.theta./sup B/=A't/sup B/,其中 A'=A(D/sub s//R/sup 2/)/sup B/,而A、A'及B是與吸附平衡等溫線的形式及吸附平衡參數無關的常數,因此對於線性與非線性的吸附平衡等溫線都可適用。
• 英文摘要： For the adsorption of phenol onto anion exchange resin Ionac AFP-329 in a finite-bath batch adsorber, the film mass transfer coefficient and intraparticle diffusivity were evaluated simultaneously by a proposed method which could be applied towards the system with a linear or moderately nonlinear isotherm. The relationships between .Ybar./Y/sup */ and time at .Ybar./Y/sub */ less than 0.2 could be expressed as .Ybar./Y/sup */=A.theta./sup B/=A't/sup B/, where A'=A(D/sub s//R/sup 2/)/sup B/, and the constants A, A' and B were independent of the types of adsorption isotherms and the values of equilibrium parameters. The values of film mass transfer coefficient and intraparticle diffusivity evaluated by the proposed method were found to be in good correlation with those determined by a nonlinear regression numerical method.
