In this study, ultrasonic-assisted removed Congo red by MOF-5/ Cu as a metal-organic framework, making the adsorption process very fast. Ultrasonic has proven to be a handy tool in accelerating dyes' adsorption by enhancing the adsorbent's affinity and the adsorbent. MOF-5 synthesized the solvothermal method and then modified it by CuCl 2 in ambient conditions. Scanning Electron Microscope (SEM), X-ray Diffraction (XRD), Fourier Transform Infrared (FT-IR), Brunauer-Emmett-Teller (BET), and Thermogravimetric analysis (TGA) were used for the identification structure and morphology of MOF-5/Cu. Sonication had an essential role in shortening the adsorption time (2 min) of Congo red by enhancing the dispersion of adsorbent (MOF-5) in solution. Congo red concentration was measured with a UV-visible spectrometer apparatus. Optimal values of Congo red concentration, Dosage of MOF-5/Cu, time, and pH were obtained by Central composite design. According to the optimal parameters, the adsorption process was very rapid. Removal of Congo red happened with excellent adsorption capacity (357.42 mg g À 1 ). Also, the MOF-5/Cu was regenerating by acetone five-time and show good results. Repeatability of the adsorption process was carried out, and the Relative Standard Deviation (RSD) was obtained 1.85 %.

In this present study, MIL-101(Fe) and amine-carbon quantum dots (CQDs) were combined by means of a post-synthetic modification (PSM) method, thus a novel MIL-101(Fe)@amine-CQDs hybrid fluorescent probe sensor for detection...

Today, energy‐environment concerns are crucial for humans. Environmental pollution will increase as a result of expanding the use of fossil fuels, nitrogen‐containing compounds (NCCs) of which cause destructive effects on the environment. In this study, adsorptive denitrogenation (ADN) was performed by adsorbing indole (IND) from model fuels and gasoline over Metal‐organic frameworks (MOFs) CuCl‐MIL‐47. The MIL‐47 was synthesized by the microwave method with modified CuCl. In the present study, the application of Central Composite Design (CCD) was evaluated in the ADN process optimization for the first time. The maximum adsorption capacity (Q0) CuCl‐MIL‐47 for indole (IND) was 769.2 mg/g. Herein, π‐complexation of IND with Cu has made a synergistic effect leading to an increase in Q0. Moreover, the reusability of CuCl‐MIL‐47 was confirmed through its regeneration via ethanol.

Cancer is one of the most difficult diseases to treat, threatening the lives of millions of people today. So far, various methods have been used to treat cancer, each having its drawbacks. One of these methods is treatment with anticancer drugs, which unfortunately have severe side effects. One of the causes of these complications is the nonspecific effects of anticancer drugs, which attack normal cells in addition to cancer cells and damage healthy tissues. In this study, we are trying to reduce the side effects and increase the efficacy of the drug by providing smart drug delivery. The metal−organic framework (MOF) was rapidly synthesized using a microwave method and at the nanoscale. The particle size of NMOF-5 was 18−20 nm, and its surface area was 2690 m 2 •g −1 . A chitosan polymer coating was formed on the nanocarrier after 6mercaptopurine was introduced. The biocompatible nanocarrier exhibited a high capacity to adsorb the drug. The biocompatible nanocarrier slowly and uniformly released 96.78% of the drug in a simulated solution at pH 5 and 20.52% at pH 7.4. This showed that CS-6-MP-NMOF-5 released the drug smartly and pH-sensitively. The stability of the biocompatible nanocarrier was studied at different pH values and remained stable at pH 5 for up to 48 h. The toxicity study of the MCF-7 cell line at different concentrations for 24 h showed the excellent performance of the biocompatible nanocarrier compared to the free drug in terms of toxicity to breast cancer cells.
