摘要
采用固相萃取-超高效液相色谱三重四级杆质谱联用法同时测定水中环丙沙星、氧氟沙星、恩诺沙星、洛美沙星、诺氟沙星等5种喹诺酮类抗生素,优化了前处理和分离检测条件。5种目标化合物在6.5 min内完成分析,在1.00μg/L～100μg/L范围内线性良好,方法检出限为0.3 ng/L～1.0 ng/L,空白和实际水样加标回收率为81.5%～116%,平行测定的RSD为6.0%～14.1%。
A rapid analytical method for simultaneous determination of five quinolones （QNs） including ciprofloxacin,ofloxacin,enrofloxacin,lomefloxacin and norfloxacin in water sample was developed. Under optimi-zing process of extraction, separation and determination,the five antibiotics were analyzed within 6.5 min. The results showed good linearity ranging from 1.00 μg/L to 100 μg/L, and detection limits of 5 QNs between 0.3 ng/L and 1.0 ng/L. The average recoveries rate of blank and real samples were in the range of 81.5 % 116% with the RSDs between 6.0% and 14.1%.
