Abstract

Abstract:

An effective method based on ultra-high performance liquid chromatography-triple quadrupole/electrostatic field orbitrap mass spectrometry (UHPLC-Q-Orbitrap MS) was developed for high-throughput screening and quantitative analysis of 112 pharmaceutical and personal care products (PPCPs) in water. The water samples were separately extracted under alkaline and acidic conditions and cleaned on an SPE column (Cleanert PEP-2). The sample was separated and detected by UHPLC-Q-Orbitrap MS, and the data were collected in full MS scan/date dependent MS2 mode. All the 112 PPCPs in water were qualitatively screened and quantified on the basis of the peak area of the precursor ion. The PPCPs showed a good linear response in the mass concentration range of three orders of magnitude (r² ≥ 0.9901), and the limits of quantification were between 0.002 μg/L and 0.8 μg/L. The recoveries of 60.1%-129.5% were achieved at different spiked levels of 0.2, 0.4, and 0.8 μg/L, and the RSDs were 1.1%-17.8% (n=6). Moreover, the method was used to screen the PPCPs in water samples acquired from seven regions of Dalian city (China), and 16 PPCPs were identified and quantified. Therefore, this simple method with high sensitivity and wide screening range can be applied to water quality management and environmental risk monitoring.

Key words: pharmaceutical and personal care products (PPCPs), screening, ultra-high performance liquid chromatography-triple quadrupole/electrostatic field orbitrap mass spectrometry (UHPLC-Q-Orbitrap MS), water
