標題: | Advances in pore morphology characterization for water treatment membranes | 作者: | Tung K.-L. Jean Y.C. Sun Y.-M. Lai J.-Y. Lee K.-R. |
公開日期: | 2010 | 來源出版物: | AIChE Annual Meeting, Conference Proceedings | 摘要: | A survey of pore size, pore size distribution and morphology characterization techniques of filtration membranes will be presented. Most of the current available techniques can provide "bulk" pore properties in the filtration membranes only and could not provide "depth" profile of the pore properties and/or three-dimensional pore structure in the multilayer filtration membranes. The presentation will be divided into two parts: in the first part, a brief review of the current methods for characterizing filtration membrane pore properties will be given; in the second part, some innovative methods can give "depth profile" properties of pore and free volume in filtration membranes from micron-scale to angstrom will be introduced. Two of those innovative methods, nano-transmission x-ray microscope (NTXM) and position annihilation lifetime spectroscopic (PALS) techniques will be illustrated thoroughly with examples of microfiltration and nanofiltration membranes. |
