n.三氯甲烷(氯仿)

The polymerization of butyl methacrylate initiated by trichloromethane and tetra-chloromethane were also discussed respectively. 同时还分别对以三氯甲烷、四氯化碳为引发剂时甲基丙烯酸丁酯的聚合反应进行了讨论。

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. 方法有条件的简化蒸馏步骤、显色剂储存使用、改变显色剂与氯仿的加入顺序、氯仿废液回收循环使用。

Solubility in trichloromethane、tetrachloromethane and carbon sulfide of the chemically modified SWNTs enhanced in comparison with the control(without modification). 经过该方法修饰的碳纳米管在三氯甲烷、四氯化碳和二硫化碳等有机溶剂中有较好的溶解性。

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,经浓缩、定容后,用毛细管气相色谱法测定。

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： 本文讨论毛细管顶空气相色谱法测定饮用水中三氯甲烷浓度测量不确定度的主要来源，并对各不确定度分量和测量结果的不确定度进行评定。
