ABSTRACT: 2,4,6-Trinitrophenol (TNP) is explosive, toxic, ecological, and a human health hazard and is resistant to degradation. It can cause symptoms such as headache, loss of appetite, dizziness, fever, nausea, diarrhea, and vomiting when inhaled. In this study, we aimed to develop a new halloysite nanotube anchored with pyrene moieties (HNT@Py) for the sensitive determination of TNP in soil, wastewater, and food samples using fully aqueous media. The HNT@Py was characterized structurally, morphologically, and thermally by using FTIR, UV-vis, XRD, TGA, fluorescence, SEM, and TEM analyses. The detection conditions for the assay were investigated and optimized, including competitive species, incubation time, sensor concentration, photostability, and selectivity. The limit of detection
