Abstract:
An analytical method was developed for the simultaneous extraction and determination of eighteen fluoroquinolones (FQs), tetracyclines (TCs) and sulfonamides (SAs) antibiotics from soils using solid phaseextraction and liquid chromatography tandem mass spectrometry.Soil sample was firstly extracted by phosphate buffer at pH 3 in combination with 50% of organic modifier acetonitrile, then purified and concentrated by SAX and HLB column.Qualitative and quantitative analysis were carried out for the analyte under the MRM mode after the chromatography separation on Kromasil C_(18)(250 mm x4.6 mm, 5 μm) column.The range of recoveries (in percent) for FQs, TCs, SAs, in the soil matrix was 67.20%-88.98%, 62.23%-85.36%, 55.76%-97.37% with 1.1%-17.2% of relative standard deviation respectively in two different concentra tions.The limits of quantification (LOQ, S/N = 3) were 3.36-8.88 jig/kg, 0.56-0.91 μg/kg and 0.07-1.85 μg/kg for FQs, TCs and SAs, respectively.This method was successfully used to detect 18 anti biotics in 6 soil samples with different land types in Tianjin.Results showed some of the antibiotics in the arable soil were detected, with concentrations of 1.72-119.57 μg/kg.
