摘要

采用溶胶-凝胶法制备了Holmium (Ho)修饰的tio2 (Ho - tio2)纳米复合材料，并将其作为有效的吸附剂和基质，利用基质辅助激光解吸/电离飞行时间质谱(MALDI-TOF MS)富集和分析双酚S和靛蓝。双酚S (BPS)和Indigo (ID)的低检出限分别为0.1 pg·mL - 1和5 pg·mL - 1。在茶叶样品中可获得极好的BPS检测，回收率为81.5 ~ 93.0%。

Holmium modified TiO₂ nanocomposites as a matrix-assisted laser desorption/ionization time-of-flight mass spectrometry matrix for the detection of bisphenol S and indigo

Holmium (Ho) modified TiO 2 (Ho–TiO 2 ) nanocomposites have been prepared by a sol–gel process, and were used as an effective adsorbent and matrix for the enrichment and analysis of bisphenol S and Indigo by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS). The low detection limits of bisphenol S (BPS) and Indigo (ID) are 0.1 pg·mL −1 and 5 pg·mL −1 , respectively. Extremely BPS detection could be achieved in tea samples with good recovery (81.5–93.0%).
