Determination of Antifungal Drugs in Water and Human Urine Samples by HPLC with Dispersive Liquid-Liquid Microextraction Based on Solidification of Floating Natural Containing Deep Eutectic Solvent Fatty Acid
A high performance liquid chromatography(HPLC) with dispersive liquid-liquid microextraction was developed for the detection of antifungal drugs,including ketoconazole,clotrimazole,terbinafine and econazole in environmental samples,based on the solidification of floating natural deep eutectic solvent(SFNADES) wihic was newly synthesized with lauric acid as the hydrogen bond donor and 1-octanol as the hydrogen bond acceptor.The extraction conditions,including extractant type and molar ratio,extractant volume,sample volume,sample pH value,ionic strength,vortex time and centrifugation time were optimized to obtain the best extraction efficiency.Under the optimal conditions,the linear ranges of four antifungal drugs(,r,2, ≥ 0.999 8) ranged from 0.56 μg/L to 500 μg/L,with limits of detection(LODs) of 0.17-0.80 μg/L,limits of quantitation(LOQs) of 0.56-2.67 μg/L,and enrichment factors of 101-114.The intra-day and inter-day realtive standard deviations(RSDs,,n ,= 6) were lower than 4.8% and 5.4%,respectively.The method was successfully applied to the detection of four antifungal drugs in real water and human urine samples with recoveries of 91.5%-107%.
