A method for simultaneous and efficient detection of multiple antibiotic residues in sludge |
| abstract |
Based on the high-performance liquid chromatography tandem mass spectrometry detection technology and combined with ultrasonic extraction and solid-phase extraction pretreatment methods, the invention provides an analysis method for simultaneously detecting multiple types of antibiotics in sludge, and belongs to the technical field of detection of trace environmental pollutants. The invention solves the problems of low recovery rate of some antibiotics, high detection cost, large amount of samples required for detection, high detection limit and the like in the existing detection methods. The antibiotic recovery rate of the invention is 75.3-130.1%, and the detection limit of the method is 1-3 μg/kg; when the sample is detected, only 0.1 g of dry sludge sample is needed; the rotary evaporation method is used to reduce the organic solvent in the ultrasonic extraction solution. Before solid-phase extraction, the volume of the ultrasonic extraction solution can be adjusted to 200 mL, which greatly reduces the column passage time of the extraction solution during the solid-phase extraction process; the present invention only uses the HLB cartridge for solid-phase extraction. While the recovery rate of the antibiotics to be tested is reduced, the testing cost is reduced. |
