Yb@TiO2 nanoparticles as a SELDI-TOF MS matrix for the simultaneous measurement of Tetrabromobisphenol A and Perfluorooctane sulfonate
MATERIALS EXPRESS(2024)
Abstract
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 center dot 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.
