Particle panetrations of membrane filters with various structures were measured with light-scattering type particle counters. Major conclusion obtained by this work are ;\n1. Interception effect acts on the filtration of particles with diamter smaller than the pore size of membrane filters.\n2. Since the difference of porosity among filters can have influence on the shape of electrostatic double layr around their collection body in deionized water system.\n3. For fiber-like membrane filters, particle penetration are subject to decrease because high ion concentration of filtration liquid compresses the electrostatic double layr around their collection body.\nThese understandings suggest that it is necessary to introduce a new index accounting for physical properties such as fiber diameter, packing density and filter thickness instead of pore size rated by the bubble point method in order to predict their collection efficiency for particles with diameter smaller than the pore size.","subitem_description_type":"Abstract"}]},"item_10007_description_14":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"研究課題/領域番号:08455366,
