摘  要:
目的:建立超声辅助原位生成离子液体分散液相微萃取(UAIS-IL-DLPME)结合HPLC分析硫酸沙丁胺醇(SAL)和盐酸莱克多巴胺(RAC)的方法。方法:采用绿色环保的亲水性离子液体1-己基-3-甲基咪唑四氟硼酸盐[C_6MIM][BF_4]和离子交换试剂双三氟甲烷磺酰亚胺锂Li NTF_2,超声辅助原位生成[C_6MIM]NTF_2,目标化合物SAL、RAC同时被萃取、富集到新生成的疏水性离子液体相中,从而达到萃取、分离和富集的效果。结果:确定最佳的萃取条件是:萃取溶剂为20μL[C_6MIM][BF_4]、离子交换剂为Li NTF_2、盐浓度为4%、分散剂为30μL四氢呋喃、超声振荡时间为35 min,离心速度和时间分别为12000 r/min和10 min,SAL和RAC的富集倍数分别为42.3和39.6,线性范围10~100 ng/mL。结论:UAIS-IL-DLPME结合高效液相色谱法进行分析,达到了在饲料及动物内脏、肌肉样品中对目标化合物SAL、RAC富集、净化和快速检测。

摘  要:
Objective: To bring forth a method that analyzes salbutamol sulfate and ractopamine hydrochloride with Ultrasonic assisted in-situ ionic liquid dispersive liquid phase microextraction( UAIS-IL-DLPME) and HPLC.Method: the environmentally-friendly ionic liquid[C_6MIM][BF_4],ion exchange agent Li NTF_2 and in-situ formation[C_6MIM]NTF_2were exploited to extract and concentrate the targeted compounds RAC and SAL in the newly generated hydrophobic ionic liquid for the sake of extraction,separation and concentration. Result: The optimal extraction conditions were determined as follows: extraction solvent for 20 μL[C_6MIM][BF_4],ion exchanger for Li NTF_2,salt concentration for 4%,dispersant for 30 μL tetrahydrofuran,ultrasonic oscillation time of 35 min,the centrifugal speed and time respectively was 12000 r / min and 10 min,SAL and RAC preconcentration factor was42.3 and 39.5,the linear range of 10 ng / m L to 100 ng / mL. Conclusion: the analysis based on the combination of UAIS-IL-DLPM-E and HPLC has helped to concentrate,purify and quickly detect the targeted compounds RAC and SAL in feed,animal innards and muscle samples.
