With the emergence and spread of coronavirus COVID-19, the use of personal cleansing, medical and household disinfectant products have increased significantly In this work, a new magnetic solid-phase extraction (MSPE) method for the determination of 11 antiseptic ingredients in surface water by high performance liquid chromatography-mass spectrometry (HPLC-MS/MS) for 6 months based on Fe3O4@PPy magnetic nanoparticles (MNPs) was established The MSPE method possessed the advantages of simple processing, little time consumption and less organic solvent consumption, and the MNPs could be reused several times The analytical parameters influencing the extraction efficiency, such as sample pH, amount of MNPs and extraction time, were optimized in detail It was indicated that the method had satisfactory linearities in the range of 0 50 to 1000 0 mu g L(-1)with the correlation coefficients (r) higher than 0 9996 Additionally, satisfactory spiked recoveries were achieved in the range of 80 21-107 33% with relative standard deviations (RSDs) from 1 98% to 8 05% The limits of detection (LODs) and limits of quantitation (LOQs) were in the range of 0 20 to 2 0 mu g L(-1)and 0 50 to 5 0 mu g L-1 Therefore, the developed MSPE-HPLC-MS/MS method has high selectivity and stability, and satisfactory quantitative capability for the antiseptic ingredients in surface water Furthermore, this method can provide relevant technical support for the development of surface water standards
