一、尿丙烯腈定量法取尿样200～5D0毫升于磨口圆底烧瓶中,加入5毫升5%丁酮水溶液及数滴硅酮与沸石。连接2支分馏柱后加热(用罩型加热器)冷凝迴流,待温度稳定后自冰水冷却试管中取2毫升馏出液。加5毫升5%丁酮水溶液于此馏出液并重复以上迴流操作,将馏出液用水稀释至5毫升。取5微升注入带有氢火熖离子化检测器的气相色谱仪定量?右阎ǘ?10～50微克/毫升)的丙
First, the urine quantitative determination of acrylonitrile Take a sample of urine 200 ~ 5D0 mill grind round bottom flask, add 5 ml of 5% butanone solution and a few drops of silicone and zeolite. Connect two fractionation columns and heat (with a hood heater) to condense and reflux. After the temperature has stabilized, take 2 ml of distillate from the ice-cooled tube. Add 5 mL of 5% butanone in water to the distillate and repeat the above reflux, diluting the distillate to 5 mL with water. Take 5 microliters injected into a gas chromatograph with a hydrogen ionization detector Quantitative? Right Yan? 10 ~ 50 micrograms / ml) of C
