The etching rate of PET film in NaOH solution was studied in order to prepare track zetched membranes (nuclepore) with proper pore diameter. Under different temperatures and NaOH concentration the bulk etching rate for PET film was determined and an empirical formula was obtained. To increase the etching rate along the tracks some effective methods are suggested. '

Authors studied the ion exchange kinetics of Sm3+ in EDTA-NH4AC (pH3.0) solution with five kinds of macrorecticular sulfonic ion exchange resin bearing same cross linkage but different Pore structure. Comparing the film diffusion constant, the particle diffusion constant, the duration of film diffusion rate-determing as well as the half exchange period, we show that the dependenceof UO22+-H+ ion exchange kinetics on pore structure of I.

Authors studied the ion exchange kinetics of Sm3+ in EDTA-NH4AC (pH3.0) solution with five kinds of macrorecticular sulfonic ion exchange resin bearing same cross linkage but different Pore structure. Comparing the film diffusion constant, the particle diffusion constant, the duration of film diffusion rate-determing as well as the half exchange period, we show that the dependenceof UO22+-H+ ion exchange kinetics on pore structure of I. E. resin as publishedin Previous paper is also applicable to the present system on the whole. Namely, proper pore size range must be relevant to attain higher particle diffusion constant while larger specific surface area leads to increace film diffusion constant.Mass transfer kinetics of Sm3+differs from UO22+ only in the manner that the duration of film diffusion rate-determing cann't be contracted by larger specific surface area probably due to a slow dissociation process of Sm-EDTA complex.

研究了Sm~(3+)在EDTA—NH_4Ac(pH=3.0)溶液和五种交联度相同但孔结构各异的磺酸型大孔离子交换树脂间的交换动力学,比较了25℃时的液膜扩散常数,粒内扩散常数、液膜扩散律速所经历的时间和半交换期,得到的结果表明,前报中关于UO_2~(2+)-H~+交换动力学与树脂孔结构间的依赖关系亦适用于本体系,即适当的孔径范围与较高的内扩散常数相联系而高的比表面会增大液膜扩散常数。与UO_2~(2+)传质不同之点在于,高的比表面不能减缩液膜扩散律速所经历的时间,这可能和Sm—EDTA络合物解离速度较慢有关。
