Abstract

En 中文

• SnO2 NPs (rutile) via surfactant-free, hydrothermal approach for PFNA and PFOS. • Adsorption-controlled surface enhances ET yielding higher currents at SnO2/CPE. • Low detection: PFNA 15.9 nM; PFOS 30.7 nM; sensitivities 58.11 and 25.03 μA μM−1·cm−2. • Field-deployable, low-cost electrochemical PFNA/PFOS screening as LC-MS/MS pre-screen.
