                                                                                                                                        將一定體積的水樣和四氯化碳由射流瓶口倒入儲樣瓶中,打開真空泵將四氯化碳和水樣通過射流瓶尾部細孔全部吸到射流瓶中。由于四氯化碳比水重,沉積在底部,細孔管將四氯化碳從儲樣瓶吸到射流瓶的底部,當水樣吸到射流瓶時,水樣已經經過四氯化碳,得到部分萃取。然后,將真空泵轉換成加壓,將四氯化碳和水樣加壓通過細孔射流激烈撞底部出口閥玻璃壁,使四氯化碳與水樣的接觸充分撞擊,增大了四氯化碳與水樣的接觸面積,達到了充分萃取的目的。  詳情 >
