【摘要】 用静态吸附研究了Co(Ⅱ)在烟草上的吸附,考察了温度、pH值、共存物及不同烟丝对吸附的影响,测定了Co(Ⅱ)的吸附等温线,级附结果能用液-固吸附中溶质计量置换模型(SDM-A)良好地描述,根据此模型计算了吸附过程中的热力学函数△G、△H和△S。更多还原

【Abstract】 The adsorption of Cobalt(Ⅱ) by tobacco has been studied by static method in this paper,and the effects of temperature、pH、coexistent substances and the different tobacco on adsorption has been shown.The adsorption isotherm has been determinated,and it can be dealt by SDM-A well,thermodynamic functions △G 、△H and △S have been accounted too.更多还原
