【摘要】 研究了静态下儿茶素在自制的聚丙烯基阴离子交换纤维上的扩散机理。结果表明,离子交换纤维对儿茶素的吸附主要以扩散而不是以交换为主控步骤,在反应的初期,以液膜扩散为主,反应3min后,以孔隙扩散控制为主。更多还原

【Abstract】 The diffusion characteristics of (+)-Catechin adsorption on self-prepared ion exchange fiber under static conditions are investigated.The results show that the control step is not the ion exchange reaction.The film diffusion gives priority to the adsorption at the initial period and after about 3 minutes the adsorption fits well into pore diffusion limitation.更多还原
