Determination of avermectin in pharmaceutical wastewater by rapid resolution liquid chromatography-tandem mass spectrometry
超快速液相色谱-串联质谱法测定制药废水中阿维菌素的研究

A method based on solid phase extraction-rapid resolution liquid chromatography-tandem mass spectrometry(SPE-RRLC-MS/MS) was developed to determine avermectin in pharmaceutical wastewater.Water samples were firstly purified through centrifugation and protein precipitation processes,and then the avermectin was enriched and purified with HLB SPE,separated through Agilent Plus C18 RRLC(rapid resolution liquid chromatography) using 0.1% formic acid solution and 50% to 90% methanol as mobile phase,and detected b...
