内容記述 | To understand the cycling of marine compounds cross flow ultrafiltration with organic membrane has been extensively used as an isolation tool to study colloids in seawater. Because organic membrane has given some contamination, a large volume sample was used for reducing contamination. Use of inorganic membrane was expected to use cross flow ultrafiltration system. Recently porous glass filter was developed as an inorganic membrane. This porous glass has specific characteristics such as high porosity, narrow width of size range, and precombustion. First, we examined a flow rate of this system and to reduce carbon free by precombustion. Second we tested recovery with a size of 30nm to use two different organic compounds : Vitamin B12 (MW=1,335), Bluedextran (MW=2,000,000). At last we used this system for isolation of organic colloids from seawater. We found a optimal flow rate of this system was 0.5〜1.0 (ml/min), and precombustion temperature was 600℃ for removal of organic contamination. Vitamin B12 could easily pass through 30nm porous glass filter, but Bluedextran could not pass through it. We confirmed this membrane can use for separation effectively. And most of DOC in seawater of Suruga Bay could pass through 30nm porous glass filter. Only 10〜20 (%) of DOC was retantated by 30nm porous glass filter. Thus a large amount of DOC in Suruga Bay was composed of a low molecular weight fraction. | |||||||
