This invention relates to the fields of environmental and bioanalytical technology, and particularly to a method for simultaneous pretreatment and detection of
bisphenol S and
bisphenol AF in biological tissues. The technical solution includes a framework process for simultaneous pretreatment and detection of
bisphenol S and
bisphenol AF in biological tissues. This invention establishes a dual-
solvent secondary extraction
system composed of n-
hexane and methyl tert-butyl
ether, achieving differentiated
adaptation to different tissue matrices. By combining the advantages of non-polar and moderately polar solvents, it can simultaneously
handle the relatively highly polar
bisphenol S and the relatively non-polar
bisphenol AF in a single extraction process. Furthermore, this method sets key physical parameters during the extraction process according to the histological characteristics of each organ. For heart and
lung tissues, specific ultrasonic power is used to ensure thorough
cell disruption; while for liver and
spleen with high
lipid content, different power and time are used to ensure the full release of lipid-bound target substances.
