提出了一种快速灵敏的荧蒽(FL)检测策略,多环芳烃(PAHs),在水样中。在这项工作中,采用注射器SPE结合固相荧光光谱法测定PAHs污染环境样品中的FL。在通过注射器SPE富集FL之后,在膜表面上直接监测荧光信号。在最优条件下,所提出的方法在2-50μg/L的浓度范围内呈线性关系,相关系数(R2)为0.998,检出限(LOD)为0.143μg/L。在实际样品中,回收率从93.47%到109.81%不等,相对标准偏差(n=3)为2.06~6.32%。根据结果,所建立的方法由于速度快,可以应用于快速检测领域,简单,便携式,高灵敏度,具有很强的抗干扰性。
A rapid and sensitive strategy was proposed for the detection of fluoranthene (FL), which is a polycyclic aromatic hydrocarbon (PAH), in water samples. In this work,
syringe solid-phase extraction (SPE) combined with solid-phase fluorescence spectrometry was used to determine FL in PAHs polluted environmental samples. The fluorescence signals were directly monitored on the membrane surface after FL was enriched by
syringe SPE. Under the optimal conditions, the proposed method showed a linear relationship in the concentration range 2-50 μg/L with a correlation coefficient (R2 ) of 0.998, and the limit of detection was 0.143 μg/L. The recoveries varied from 93.47% to 109.81% in the actual samples, with the relative standard deviations (n = 3) ranging from 2.06% to 6.32%. According to the results, the established method can be applied in the field of rapid detection as it is fast, simple, portable, and highly sensitive, and has strong anti-interference.
