This work presents a novel, strong and efficient adsorbent (CS@TDI@EDTA@γ-AlO(OH)) prepared through the green process using three components, chitosan, BNPs EDTA amide ester bridges. An eco-friendly easy approach was used for preparation of this novel adsorbent, low cost, access to materials, simplicity method are some interesting advantages work. Also, as an remove diazinon organophosphate poison tetracycline antibiotic from aqueous solutions. In order confirm structure, CS@TDI@EDTA@γ-AlO(OH) composite investigated by various analyses including FT-IR, EDX, XRD, FESEM TGA. The adsorption behavior removal under different conditions varying concentration, temperature, dose, pH contact time. Based on tests, highest capacity obtained 0.12 g/L at 7 60 °C with 40 mg/L initial concentration. maximum 9 30 equilibrium results were in good accordance Langmuir Freundlich isotherm models, respectively. capacities 1428.5 555.5 mg/g, Also kinetic investigations revealed that correlation factor (R2) pseudo-second-order model 0.9986 0.9988, while coefficient k (g/mg.min) 0.000084 0.0033, These indicate is kinetics model. Formation hydrogen bonds between adsorbate well high specific surface area porosity main mechanisms contribute process. addition, thermodynamic studies indicated spontaneous endothermic expected have wide range applications wastewater treatment thanks its reusability water compared other adsorbents.

Presently, the main cause of pollution natural water resources is heavy metal ions. The removal ions such as nickel (Ni 2+ ) and cadmium (Cd has been given considerable attention due to their health environmental risks. In this regard, for wastewater treatment containing ions, graphene oxide (GO) nanocomposites with nanoparticles (NPs) attained significant importance. study, stacked copper (GO/CuO-NCs) were synthesized characterized by Fourier transform infrared (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive (EDX), atomic force (AFM) analytical procedures. prepared GO/CuO-NCs applied Ni Cd from a binary ion system in batch continuous experiments. obtained results revealed that exhibited highest efficiencies (89.60% ± 2.12%) (97.10% 1.91%) at optimum values pH: 8, dose: 0.25 g, contact time: 60 min, 50 ppm initial concentration study. However, 4 mL/min flow rate, concentration, 2 cm bed height proved be suitable conditions adsorption column kinetic data best fitting pseudo-second-order model. isotherm provided best-fitting Langmuir This study suggested GO/CuO have efficient adsorbents system.
