“…30,31 The spectrum of H 2 -SDBA shows another band peaking at 937 cm −1 due to aromatic ring deformation and C-S stretching; this band cannot be seen in the spectrum of Cu 3 (SDBA) 2 (HSDBA), which may indicate bonding between the ligands and the metal nodes. The spectrum of Cu 3 (SDBA) 2 (HSDBA) shows an additional band, peaking at 519 cm −1 and corresponding to the vibrational signal of Cu-O, 32 thereby confirming the formation of Cu 3 (SDBA) 2 (HSDBA) via Cu-O bonds between the metal nodes and the organic ligands.…”

“…Research has shown that functionalization of MOFs with amine groups can significantly increase their chemical stability [23]. In addition, modification of MOFs with amine groups increases the number of electron-rich nitrogen sites, which results in more positive charge in the MOF structure [24]. Some MOFs functionalized with amine groups such as Uio-66-NH2 [25], NH2-Cu-MOF [26], amino-functionalized MOF-5 [27] have recently been studied to remove various water contaminants.…”

An amino-functionalized MIL-68(Al) metal-organic framework (amino-MIL-68(Al) MOF) was synthesized by solvothermal method and then characterized by FESEM, XRD, FTIR, EDX-mapping, and BET-BJH techniques. In order to predict arsenate (As(V)) removal, a robust quadratic model (R2 > 0.99, F-value = 2389.17 and p-value < 0.0001) was developed by the central composite design (CCD) method and then the genetic algorithm (GA) was utilized to optimize the system response and four independent variables. The results showed that As(V) adsorption on MOF was affected by solution pH, adsorbent dose, As(V) concentration and reaction time, respectively. Predicted and experimental As(V) removal efficiencies under optimal conditions were 99.45 and 99.87 %, respectively. The fitting of experimental data showed that As(V) adsorption on MOF is well described by the nonlinear form of the Langmuir isotherm and pseudo-second-order kinetic. At optimum pH 3, the maximum As(V) adsorption capacity was 74.29 mg/g. Thermodynamic studies in the temperature range of 25 to 50 °C showed that As(V) adsorption is a spontaneous endothermic process. The reusability of MOF in ten adsorption/regeneration cycles was studied and the results showed high reusability of this adsorbent. The highest interventional effect in inhibiting As(V) adsorption was related to phosphate anion. The results of this study showed that amino-MIL-68(Al) can be used as an effective MOF with a high surface area (> 1000 m2/g) and high reusability for As(V)-contaminated water.

“…The solution turned into blue crystals which was further filtered and washed with ethanol and water and again dried in oven at 418 K for 12 hours. The MOF was activated by immersing in methanol for 24 hours and afterward dried at 418 K [37].…”

The electrochemical detection of ciprofloxacin (CIP) using copper metal organic framework (Cu BTC) is reported. The glassy carbon electrode was used as a base electrode which was further modified with Cu BTC and differential pulse voltammetry technique was adopted for electrosensing. Under optimized conditions, a linear response for CIP was obtained in concentration range from 1×10−8 to 20×10−6 mol L−1 with a limit of detection of 0.47×10−9 mol L−1. Moreover, the proposed electrosensor showed acceptable reproducibility with 2.39 % relative standard deviation. Determination of CIP in tap water samples showed good recovery in range of 94.6–108 %.
