Abstract: =10） ranged from 2.77 μg/L to 9.93 μg/L. The method was then applied to the analysis of real water samples. Three types of water were tested： tap water，rainwater，and landscape lake water. Recovery tests were conducted at two spiked concentration levels，namely 10 μg/L and 100 μg/L. The average recoveries of the three target analytes ranged from 75.6% to 128.5%. The relative standard deviations，calculated from three replicate measurements，were between 1.3% and 9.4%. These results confirm that the method is accurate，reliable，and applicable to complex aqueous matrices. Compared with previously reported methods for TC analysis，the present approach offers several distinct advantages. It requires significantly less adsorbent. It also simplifies the operational procedure by eliminating time-consuming steps. Importantly，these improvements are achieved without sacrificing sensitivity or accuracy. In summary，this study provides a robust，convenient，and efficient analytical solution for monitoring trace levels of TCs in environmental water. Furthermore，the design and synthesis strategy of this multifunctional magnetic adsorbent offers new insights for developing advanced functional materials for environmental sample preparation.
