The method based on the dispersive solid-phase extraction (DSPE) by novel molybdenum disulfide modified with carbon dot (MoS₂/CD) composite combined with high-performance liquid chromatography (HPLC) was developed for the determination of three brominated flame retardants (BFRs), including tetrabromobisphenol A (TBBPA), tetrabromobisphenol A bisallylether (TBBPA-BAE), and tetrabromobisphenol A bis(2,3-dibromopropyl ether) (TBBPA-BDBPE). Owing to the stacked planar structure and large surface area of MoS₂, a large number of CDs can be easily loaded on the surface of MoS₂. Benefiting from good dispersing capability of MoS₂, similar density with analytes, and hydrogen bonds between CDs and the target analytes, the CDs on the surface of MoS₂ as sorbent for the DSPE procedure exhibited good extraction performance. Under optimal conditions, application of the developed method to analyze BFRs from real water samples resulted in good recovery values ranging from 80 to 91% with relative standard deviation (RSD) values lower than 6.5%. Limits of detection (LODs) were in the range of 0.01–0.06 μg/L. The result above showed that the method has potential for the extraction and detection of trace-level BFRs from real water sample.

建立了基于新型碳点修饰的二硫化钼（MoS ₂ / CD）复合物与高效液相色谱（HPLC）的分散固相萃取（DSPE）方法测定三种溴化阻燃剂（BFRs）的方法），包括四溴双酚A（TBBPA），四溴双酚A双烯丙基醚（TBBPA-BAE）和四溴双酚A双（2,3-二溴丙基醚）（TBBPA-BDBPE）。由于堆叠的平面结构和MoS _2的大表面积，可以将大量CD轻松装载到MoS ₂的表面上。受益于MoS _2的良好分散能力由于与分析物具有相似的密度，并且CD与目标分析物之间存在氢键，因此，作为DSPE程序吸附剂的MoS ₂表面CD表现出良好的萃取性能。在最佳条件下，使用开发的方法分析真实水样中的BFR可获得良好的回收率，范围从80％到91％，相对标准偏差（RSD）值低于6.5％。检出限（LOD）在0.01-0.06μg/ L的范围内。以上结果表明，该方法具有提取和检测实际水样中痕量BFR的潜力。
