n.三氯甲烷(氯仿)

The polymerization of butyl methacrylate initiated by trichloromethane and tetra-chloromethane were also discussed respectively. 同時(shí)還分別對(duì)以三氯甲烷、四氯化碳為引發(fā)劑時(shí)甲基丙烯酸丁酯的聚合反應(yīng)進(jìn)行了討論。

Methods Omit and alter some work procedure including distillation,store reagent that show color,either the order of reagent procedure or recycle of the waste trichloromethane. 方法有條件的簡(jiǎn)化蒸餾步驟、顯色劑儲(chǔ)存使用、改變顯色劑與氯仿的加入順序、氯仿廢液回收循環(huán)使用。

Solubility in trichloromethane、tetrachloromethane and carbon sulfide of the chemically modified SWNTs enhanced in comparison with the control(without modification). 經(jīng)過(guò)該方法修飾的碳納米管在三氯甲烷、四氯化碳和二硫化碳等有機(jī)溶劑中有較好的溶解性。

Using acetone adds the water withdraws the atrazine in the soil, than extract with trichloromethane, after concentrated and settle to permit, use the capillary gas chromatography. 采用丙酮加水提取土壤中的阿特拉津,再用三氯甲烷萃取,經(jīng)濃縮、定容后,用毛細(xì)管氣相色譜法測(cè)定。

Abstract： The main sources of uncertainty of measurement for determination of trichloromethane in drinking water by headspace capillary GC were discussed in this paper. 摘 要： 本文討論毛細(xì)管頂空氣相色譜法測(cè)定飲用水中三氯甲烷濃度測(cè)量不確定度的主要來(lái)源，并對(duì)各不確定度分量和測(cè)量結(jié)果的不確定度進(jìn)行評(píng)定。
