ABSTRACT
p-Nitroaniline ( PNA) was one kind of highly toxic aromatic amine and becomes an environmental pollutant in recent years. Here we reported the construction of a fluorescent sensor based on an anionic pyrene, 8-hydroxypyrene-1,3,6-trisulfonic acid trisodium salt (HPTS), for the rapid and visual detection of PNA in aqueous media. The fluorescence quenching of HPTS caused by the presence of PNA was through non-covalent interactions. A good linear relationship between fluorescent intensity of HPTS at 512 nm was obtained in the range of 10-120 μmol/L. The detection limit (3σ) of this approach was 4. 6 μmol/L. The results showed that the method was suitable for rapid detection of PNA in real samples with good sensitivity, selectivity, anti-interference, low cost and easy operation.
