La-SnO 2 NF/CNTs/GCE was successfully applied to electrochemically detect bisphenol A (BPA, an environmental pollutant), and the linear range and the detection limit is 0.02 ∼ 10 μmol/L and 1.02 nmol/L respectively. Moreover, the recovery rate is 96% ∼ 104% in actual water samples and the results are satisfactory. • La-doped hierarchical nanoflower-like SnO 2 composited with carbon nanotubes (La-SnO 2 NF/CNTs) was synthesized. • This electrode material was successfully applied in bisphenol A (BPA) electrochemical rapid detection. • The recovery rate is 96 % ∼ 104 % in actual sample analysis. Lanthanum-doped nanoflower-like tin dioxide was successfully synthesized by hydrothermal method and composited carbon nanotubes (La-SnO 2 NF/CNTs), then it was loaded onto glassy carbon electrode (GCE) to electrochemically detect bisphenol A (BPA). The experimental results show that La-SnO 2 NF/CNTs/GCE has excellent electrochemical performance, and linear range, detection limit and quantification limit are 0.02 ∼ 10 μmol/L, 1.02 nmol/L and 0.02 μmol/L respectively. The precision and accuracy of this method are verified by intra-day and inter-day. Finally, La-SnO 2 NF/CNTs/GCE was further applied to determine BPA in actual water samples and recovery rate was 96 % ∼ 104 %, suggesting it has huge potential in BPA determination.
