A novel 3-amino-5-mercapto-1,2,4-triazole functionalized graphene oxide composite (GO-ATT) was successfully prepared via a covalent coupling method, then employed for the removal of p-nitrophenol (PNP) from wastewater. The morphology as well composition GO-ATT were investigated using Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), X-ray diffraction (XRD), and photoelectron (XPS). surface charge evaluated by Zeta potential analyses. area pore size distribution analyzed specific analyses Brunauer–Emmett–Teller (BET) method. Batch adsorption experiments performed to investigate effects conditional factors, including contact time, solution pH, initial PNP concentration, temperature, on process. maximum capacity (0.287 mmol g−1) could be obtained at 25 °C. Freundlich isotherm (R2 > 0.92505) can better describe behavior composite. thermodynamic functions (ΔG°, ΔH°, ΔS°) indicate that is spontaneous, endothermic, entropy-increasing process features physisorption. conformed nonlinear pseudo-second-order kinetic model. Adsorption mechanism investigation indicated electrostatic, π-π stacking, hydrogen bonding interactions involved in After 10 adsorption–desorption cycles, adsorbent exhibited stable efficient rate (94%) PNP. Due its advantages high efficiency, excellent reusability, stability, covalently coupled might used an effective phenolic contaminants
