应用多孔玻璃膜分离水中纳米有机胶体质的研究
- Isolating the nano-colloids using cross-flow ultrafiltration technique with porous glass membrane
- 摘要：应用新型的硼硅酸多孔玻璃膜(porousglass)于错流超滤(crossflowultrafiltration)系统中,分离出30-300nm有机质胶体.分别试验孔径为30nm、50nm和100nm等多孔玻璃膜对一些标准有机大分子的截留率.实验结果显示过滤溶液的酸度、温度、盐度对该分离膜的分离性能影响甚微.
- Abstract：The porous glass membrane produced by Sumica Chemical Company of Japan was applied to cross flow ultrafiltration. In different filtering conditions including pressure, circle flow rate, acidity, temperature and salinity, the behaviors of porous glass membrane were investigated. The results showed the membrane is suitable to isolate the organic colloids from nature water. The retention varied with the pore size of porous glass membrane used.
