Abstract
- [Display omitted] • S-CTFs nanospheres was prepared and used to build an electrochemical sensor. • Nickel cobaltite (NiCo 2 O 4) nanoflowers were in situ formed on S-CTFs. • S-CTFs@NiCo 2 O 4 modified electrode exhibited the outstanding synergetic effect of S-CTFs and NiCo 2 O 4. • The sensor showed high sensitivity for simultaneous detection of ACOP and 4-AP. Owing to the high toxicity of acetaminophen (ACOP) and 4-aminophenol (4-AP) when they are overused, the simultaneous determination of ACOP and 4-AP is crucial. In this present paper, an electrochemical sensor based on the nanocomposite of sulfurbridged covalent triazine frameworks (S-CTFs) and in situ formed nickel cobaltite (NiCo 2 O 4) nanoflowers on S-CTFs, denoted as S-CTFs@NiCo 2 O 4 , was fabricated for the first time for sensitive detection of ACOP and 4-AP. S-CTFs@NiCo 2 O 4 modified electrode exhibited the outstanding synergetic effects of S-CTFs (prominent enrichment ability and large surface area) and NiCo 2 O 4 (excellent electrocatalytic activity). The developed electrode had the advantages of high reproducibility, repeatability, anti-interference and stability, and it exhibited a wide linear concentration range (2 ∼ 360 μM) and a low limit of detection (0.18 μM and 0.35 μM) for ACOP and 4-AP, respectively. In addition, the designed electrochemical sensor was evaluated towards the detecting ACOP and 4-AP in real samples with satisfactory recovery, illustrating that electrode has a broad prospect in the clinical application.
