Decontamination of water from antibiotic drugs or their metabolites using an adsorption technique represents a great challenge with respect to high adsorption capacity and cost effectiveness. Antibiotic drugs are generally released in water resources after human use, and these may be classified under the category of hazardous materials or persistent organic pollutants. Therefore, the present study is aimed to explore the removal of doxycycline (DCN) antibiotic drug by novel assembled chemically modified metal–organic frameworks in the form of NTiO2/NiSA-(Si-TETA)-Cu(II) nanocomposite. Effects of some parameters such as pH (2–10 range), contact time (1–60 min), nanocomposite doses (5–100 mg), drug concentrations (5–100 mg L–1), ionic strength (0.1–1.0 mol L–1 of NaCl), and reaction temperatures (25–55 °C) on the removal efficiency of DCN drug have been investigated, optimized, and evaluated. A complex formation between DCN drug and NTiO2/NiSA-(Si-TETA)-Cu(II) nanocomposite has been proposed as the contributing master mechanism, as carefully confirmed from the kinetics, isotherm, and thermodynamic studies. The kinetics and isotherm data were described by the pseudo-second-order and Langmuir models. The maximum identified adsorption capacity values were as high as 473.05, 562.08, and 682.15 mg g–1 at 25, 40, and 50 °C, respectively. The removal efficiency values of DCN drug from water matrices by the action of NTiO2/NiSA-(Si-TETA)-Cu(II) nanocomposite were in the range 97.05 to 99.71% to elucidate that the NTiO2/NiSA-(Si-TETA)-Cu(II) nanocomposite can be applied for the removal of DCN drug from real wastewater samples.

A spherical cellulose-based adsorbent (2-AMP resin) functionalized by 2-aminomethyl-pyridine was prepared via the radiation grafting technology. The adsorption behavior of the 2-AMP resin for Ag(I) recovery was assessed by batch and column experiments. The adsorption isotherm was best represented by Langmuir isotherm, and the adsorption capacity of the 2-AMP resin was 110.5 mg/g. The adsorption kinetics was found to follow the pseudo-second-order kinetic model. Moreover, the adsorbent presented good selectivity for Ag(I) from the coexisting ions [Ca(II), Mg(II), Ni(II), and Zn(II)] both in the batch and column experiments. The adsorption efficiency was unchanged even when the NaNO3 concentration was about 3000 fold higher than Ag(I). The interactions between the 2-AMP resin and Ag(I) were interpreted through XPS analysis, and the adsorption mechanism was proved to be a chelation interaction between aminomethyl-pyridine groups and Ag(I). It is demonstrated that the 2-AMP resin would have a splendid potential for the recovery of Ag(I).

“…22 Although there are many treatments for metal ions, few literatures for Mn(VII) are available. [23][24][25] Investigations and studies have shown that the separation of adsorbents accounts for 75% of the overall operating costs. Due to the strong magnetic properties of Fe 3 O 4 , it can be quickly separated from the solution.…”

Magnetic Fe3O4/MnO2/TiO2/polypyrrole (PPy) heterostructure as adsorbent for adsorbing Mn7+ was synthesized by combining hydrothermal method and chemical oxidation method. The heterostructure was characterized by field‐emission scanning electron microscope, Fourier transform infrared spectroscopy, X‐ray diffraction, and vibrating sample magnetometer. Its saturation magnetization is 18.88 emu/g, so it is easy to separate it from the solution. The feasibility of Fe3O4/MnO2/TiO2/PPy heterostructure to remove Mn7+ was researched in detail. It is found that the optimal pH is 2. The initial adsorption rate can reach 4.60 mg/g min. At 288.15 K, the maximum equilibrium adsorption capacity is 202.8 mg/g. Adsorption kinetics follows a pseudo second order model, as well as is determined by through membrane diffusion processes. The Langmuir isotherm model is used to describe the adsorption isotherm behavior. Besides, thermodynamic parameters indicate spontaneous adsorption behavior, and entropy of the endothermic reaction increases. Finally, the cycle test results show that the adsorbent has better cycle performance, displaying broad application prospects.
