“…The Langmuir adsorption isotherm takes into describes the homogenous surface that a single surface site of adsorbent is occupied by a single adsorbate molecule. The Langmuir isotherm assumes that there is not any lateral interaction between the adsorbed molecules [39]. Langmuir, Temkin, and Freundlich isotherm represent according to the following Equations (3-5):…”

In this work, Cd MOF has been prepared using a hydrothermal method and characterized by the SEM, elemental mapping, XRD, EDS, and BET analysis. The diazinon stability has been investigated in various pH (4-8) and temperature (298oK – 323oK) using UV-Vis spectrometer in the range of 230 – 280 nm, at its main absorption peak at 247 nm. Adsorption behaviors of diazinon on the Cd MOF were considered in different conditions. UV-Vis spectroscopy was used to monitor the removal of diazinon using the Cd MOF. The adsorption capacity of 138 mg g-1 was obtained. The effect of temperature (298 K -323 K), pH (4-8), adsorbent dose (1-7 mg), initial concentration (4-12 mg L-1), stirring speed (0-500 rpm), and adsorption kinetics were studied using batch rout. All the studied parameters have shown significant effects on the efficiency of removal of diazinon by the Cd MOF. The adsorption thermodynamic was investigated in the temperature range of 298 k to 323 K and it has shown the endothermic nature of adsorption of diazinon using prepared Cd MOF. The adsorption isotherm follows by the Langmuir isotherm model. It was demonstrated that synthesized adsorbent could be effectively used for the removal of diazinon from water.

Cobalt/copper-based bimetallic metal−organic frameworks (Co/Cu-MOFs) are synthesized using two organic ligands in the presented research work. Subsequent incorporation of bismuth oxyiodide (BiOI) into the MOFs via a hydrothermal approach formed composite materials (Co/Cu-MOFs@BiOI) that exhibit an efficient photocatalytic activity. The synthesized materials were thoroughly characterized by using X-ray diffraction, Fourier transform infrared, and scanning electron microscopy techniques. Co/Cu-MOF @BiOI was employed as a novel photocatalyst for the degradation of cationic methylene blue (MB) dye in aqueous solution under visible light. The combination of Co/Cu-MOFs with BiOI significantly enhanced the photocatalytic degradation efficiency of MB relative to that of bimetallic MOFs (Co/Cu-MOFs) owing to increased visible light absorption and reduced charge-carrier recombination. A Box−Behnken design (BBD) statistical study is employed in conjunction with response surface methodology (RSM) to optimize the dye degradation process. The BBD-RSM methodology successfully identified the optimal dye degradation conditions, including an initial dye concentration of 6 ppm, irradiation time of 120 min, and catalyst dosage of 0.14 g L −1 . Furthermore, the predicted coefficient of regression (R 2 ) value under these optimal conditions using BBD-RSM was 99%, indicating a strong correlation between the prediction and experimental observation. These results demonstrate the strong potential of the Co/Cu-MOF @BiOI composites as efficient photocatalysts for the removal of organic dyes.

“…Methylene blue (MB), a typical cationic dye, is a heterocyclic aromatic compound containing sulfur and is most commonly used in various fields including textiles, rubbers, varnishes, and medicals. This toxic organic dye may result in a variety of health issues such as cancer, hemolytic anemia, hypertension, skin staining, precordial pain, and injection site necrosis [18][19][20]. For these reasons, MB dye-containing wastewater is classified as hazardous waste and must be treated before being discharged into the water supply.…”

Modeling and simulation of batch adsorption of the organic dye methylene blue (MB) by modified metal‐organic framework‐5 (MOF‐5) were investigated. The reported data on the adsorption of MB dye onto Wells‐Dawson acids (H6P2W18O62)‐immobilized MOF‐5 were employed. The film‐pore diffusion model was developed based on external mass transfer coefficient and pore diffusion coefficient that govern the mass transfer process in batch organic dye adsorption. Applying the estimated parameters, the MB adsorption by using modified MOF‐5 was examined to evaluate the effects of MOF‐5 modification, initial dye concentration, temperature, and the dosage of adsorbent. The adsorption capacity of modified MOF‐5 (H6P2W18O62/MOF‐5) was higher than pure MOF‐5. Besides, a lower initial MB dye concentration, higher temperature, and lower adsorbent dosage resulted in higher MB dye adsorption capacity.
