“…For example, the reported maximum adsorption efciency of cellulose nanocrystals (CNCs) [40] and cellulose nanofbril aerogels [41] to MG was 212.7 mg/g and 243.9 mg/ g, respectively. Apart from MNPs, CNTs, and cellulosebased nanomaterials, several other nanocomposites also showed high adsorption efciency to MG, such as nanoiron oxide-loaded alginate microspheres [35], zeolite nanostructures [42], iron nanoparticles loaded on ash [43], bimetallic Fe-Zn nanoparticles [44], kappa-carrageenan-gpolyacrylic acid/TiO 2 -NH 2 hydrogel nanocomposite [45], gum xanthan/psyllium-based nanocomposite [46], and hematite-reduced graphene oxide composites [47]. In addition, reports using graft copolymer derived from amylopectin and poly(acrylic acid) [48], graphite oxide/polyurethane foam material [49], chitosan beads [50], and reinforced hybrid porous beads that are prepared with alginate, aluminumpillared montmorillonite, polyvinyl alcohol, and CaCO 3 [51] for MG removal also exist in literature.…”

Malachite green (MG) residue in aquatic products is a widely concerning issue, and the possible source of MG contamination includes its illegal usage and environmental pollution. A variety of strategies for solving such a problem have been proposed, and the research about them is summarized in this review. The MG contamination in aquaculture environments can be eliminated by adsorption, degraded by advanced oxidation processes (AOPs), or biodegraded by microbes or enzymes. The illegal usage of MG can be prevented by screening novel anti-Saprolegnia sp. agents from current available agricultural antibiotics, plant extracts, or antagonistic microbes. Nevertheless, deficiencies also existed in these proposed solving strategies. Therefore, further research opportunities in such areas were provided. This includes developing effective combinatorial methods (adsorption + AOPs or biodegradation) for eliminating MG from the aquaculture environment; systematically considering the impact of practical conditions on the efficiency of MG elimination; screening more efficient anti-Saprolegnia sp. agents; and systematically evaluating both the in vivo activities and safety of these agents.

“…This sulfurcontaining heterocyclic aromatic compound is frequently used across numerous industries, including the leather, paper, textile, pharmaceutical, and cosmetic industries. 4 Inadequate containment measures lead to the discharge of organic dyes and their precursors, posing a significant health hazard to both humans and wildlife due to their elevated levels of toxicity and carcinogenic properties. 1 Methods and technologies for the removal of organic dyes from aqueous solutions are urgently required to overcome such environmental issues.…”

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 18–20. For these reasons, MB dye‐containing wastewater is classified as hazardous waste and must be treated before being discharged into the water supply.…”

Modeling of Batch Organic Dye Adsorption Using Modified Metal‐Organic Framework‐5

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.
