中文摘要:
      采用固相萃取/高效液相色谱-三重四级杆质谱法同时测定医疗废水中的20种超痕量抗生素残留,通过优化试验条件,使方法在100μg/L~100μg/L范围内线性良好,方法检出限为024ng/L~122ng/L。空白水样和实际水样3个质量浓度水平的加标回收率分别为80.2%~108%和75.8%~114%,6次测定结果的RSD分别为2.4%~8.4%和1.7%~8.1%。将该方法用于测定重庆市2家三甲医院医疗废水中的超痕量抗生素残留,结果有11种抗生素检出,其余均为未检出。
英文摘要:
      20 kinds of ultra trace antibiotic residues in medical wastewater were determined by solid phase extraction high performance liquid chromatography triple quadrupole mass spectrometry. By optimizing the experimental conditions, the method had good linearity in the range of 1.00μg/L~100μg/L. The method detection limits were from 0.24ng/L to 1.22ng/L. The recoveries of spiked blank and actual samples with three mass concentration levels were 80.2%~108% and 75.8%~114%, respectively, and the RSDs of six measurements were 2.4%~8.4% and 1.7%~8.1%, respectively. This method was used to determine ultra trace antibiotic residues in the medical wastewater from two Three A hospitals in Chongqing, the results showed that 11 antibiotics were detected and the rest were not detected.
