According to the frequently used methods of extraction and isolation of natural products from organic body, the freeze - dried ascidian tunica was exhaustively extracted with 100 % chloroform then the combined extracts were filtered and the solvent was separately concentrated under vacuum to yield a dark - brown gum
按照目前比較常用的天然產物的提取分離辦法，將樣品冷凍乾燥后，用100氯仿浸泡，收集氯仿濾液，減壓蒸餾濃縮去除浸提溶劑，得到黑褐色的浸膏狀物質。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 investigation showed that nanofiltration membrane with good character can be made when concentration of coating solution is 1 % - 2 %, coating time is 1 hour, concentration of cross - linking agent is 0. 5 % and cross - linking time is 5 hours
研究表明塗層液濃度在1 2 ，浸塗時間1h ，交聯劑濃度為0 . 5 ，交聯時間5h的條件下可以得到性能較好的納濾膜。Technique and condition of developing membrane such as thickness of support layer, concentration of coating solution, coating time, ph value of coating solution, concentration of small molecular additive in coating solution, concentration of cross - linking agent, cross - linking time and composite times were studied
對制膜工藝條件如基膜厚度、塗層液濃度、浸塗時間、塗層液ph值、塗層液中小分子添加劑的含量、交聯劑類型、交聯劑濃度、交聯時間及復合次數對納濾膜性能的影響進行了研究。Take a portion of a well isolated colony from each of the dishes and streak onto a filter paper moistened with the oxidase reagent or use commercially available test kits according to the recommendations of the supplier
