液液萃取

• This method is to obtain multi - fungi from water and waster water by methylene chloride fluid - fluid extract nitrogen , and then take the concentration purification to the highly effective liquid phase color spectrometer where it can be detected by the diode matrix detector
  摘要用二氯甲烷液液萃取氮吹浓缩法萃取水和废水中的多菌灵，取浓缩纯化后的有机相直接进样到高效液相色谱仪，用二极管矩阵检测器检测，根据保留时间外标法定量。
