▎ 摘　　要

In this study, nanoscale zero-valent iron (nZVI) coupled with graphene oxide (GO) and copper (Cu) was syn-thesized and evaluated to develop an efficient adsorbent for the simultaneous removal of Direct Red 81 (DR 81) and bisphenol A (BPA) from aqueous environments. The adsorbent was characterized by field emission scanning electron microscopy (FESEM), energy dispersive X-Ray (EDX), Fourier-transform infrared spectroscopy (FTIR), Brunauer-Emmett-Teller (BET), and vibrating sample magnetometer (VSM). The particle size distribution (PSD) findings demonstrated that the average size of nZVI-GO-Cu was equal to 20.89 nm. The maximum removal ef-ficiency (97.50%) was obtained at optimized conditions, including pH of 5, the adsorbent dosage of 0.5 g, contact time of 35 min, and initial concentration of 5 mg L-1. The experimental data were investigated using the Langmuir and Freundlich isotherm models. The Langmuir model was revealed to be a better model (R2 = 0.9993), and the adsorption of DR 81 was found to be most desirable on nZVI-GO-Cu with a maximum adsorption capacity (qmax) of 21.32 mg g-1. Also, the adsorption kinetics models were assessed and the resulting data fitted well with a pseudo-second-order (PSO) kinetic model with R2 equal to 0.9991. All in all, the present results indicate that this environmentally friendly, efficient, and inexpensive adsorbent can be useful for the simulta-neous elimination of DR 81 and BPA from aqueous media.
