摘要

采用溶胶-凝胶法合成的镱修饰二氧化钛纳米粒子（Yb@TiO2）被用作一种高效吸附剂和基质，通过表面增强激光解吸电离飞行时间质谱（SELDI-TOF MS）分析全氟辛烷磺酸（PFOS）和四溴双酚A（TBBPA）。全氟辛烷磺酸和四溴双酚 A 的检测限均为 0.01 pg -mL-1。山茶油样品的分析结果表明，回收率较高（80.3%-86.8%），TBBPA 的检出限较低。

Yb@TiO2 nanoparticles as a SELDI-TOF MS matrix for the simultaneous measurement of Tetrabromobisphenol A and Perfluorooctane sulfonate

Ytterbium modified TiO2 nanoparticles (Yb@TiO2), synthesized by a sol–gel process, were employed as an efficient adsorbent and matrix for the analysis of Perfluorooctane sulfonate (PFOS) and Tetrabromobisphenol A (TBBPA) via surface-enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF MS). The detection limits for PFOS and TBBPA are achievement with 0.01 pg ·mL−1. The results of the analysis of camellia oil samples show good recovery (80.3%–86.8%) with a low detection limit for TBBPA.
