The present work indicates the organic nf membranes and the inorganic nf membranes all have shortages, so develop composite nf membranes that have low cost, mechanically strong and thermally / chemically - resistant, easy to cleanout and good performances is a very important task. in this paper, the preparation of inorganic - organic composite nf membranes were presented. this composite comprise a porous sio2 / al2o3 support substrate, the pore diameters of which ranging from 10 to 15 nm, this inorganic support substrate having a polymer membrane which comprises an polyvinyl alcohol ( pva ) or polyamide ( pa ) densely deposited on at least one of the face surfaces thereof, the structural porosity of such pva and pa membrane ranging from 3 to 5 nm
本論文以開發無機?有機復合納濾膜為出發點,首先在al _ 2o _ 3多孔微濾膜上利用溶膠?凝膠法制備sio _ 2 al _ 2o _ 3無機復合超濾膜作為無機?有機復合納濾膜的基膜;選用聚乙烯醇和聚酰胺為表面功能層材料,分別探討了以羥基丁二酸和磺基水楊酸為混合交聯劑,採用浸塗法制備了聚乙烯醇sio _ 2 ? al _ 2o _ 3復合納濾膜;以均苯二甲酰氯、哌嗪和二胺為單體,採用界面聚合法制備了聚酰胺sio _ 2 ? al _ 2o _ 3復合納濾膜,並對影響膜性能的諸多因素進行系統研究。The main research contents and results are as follows : ( 1 ) disc papers and oxford cups were used to ascertain bacteriostatic effect of hongqu. using 70 % ethanol and water as solvent, the extraction inhibited bacillus subtilis, bacillus cereus and staphylococcus aureus and had no effect on e. coli, salmonella. typhi, yeasts and algae
主要研究內容和結果如下: ( 1 )利用濾紙片法和管碟法確定了紅曲的抑菌譜:紅曲70乙醇和水溶液浸提物對蠟樣芽孢桿菌、枯草芽孢桿菌等革蘭氏陽性菌具有較強的抑制作用,對革蘭氏陰性菌、黴菌和酵母菌沒有抑制效果。The crude extraction of dry pea seed, which was obtained through marination, homogenization, filtration, centrifugation and other methods, was precipitated by 50 mmol / l ( final concentration ) mgq2. the pellet was chromatographed on aca ^ gel filtration and deae - cellulose 52 ( de 52 ) anion - exchanger. single eluting peak containing ferritin was obtained finally
2 、豌豆種子鐵蛋白的純化豌豆種子經浸泡、勻漿、過濾、離心等操作得到豌豆鐵蛋白粗提液,再用終濃度為50mmol / l的mgcl _ 2鹽析等處理后,經aca _ ( 22 )凝膠過濾柱層析和deae -纖維素52 ( de52 )陰離子交換柱層析等方法進行純化,得到單一的豌豆鐵蛋白洗脫峰。
