The application of a novel composite MIL88A(Fe)/TiO2 for phenol removal in a new hexagonal photoreactor design was investigated. The unique hexagonal shape of the reactor increases the surface area available for irradiation, leading to more efficient removal of contaminants. The composite was characterized using X ray diffraction (XRD), Fourier transform‐infrared spectroscopy (FTIR), and scanning electron microscopy (SEM) images to determine its properties. Photocatalyst dosage, reaction time, phenol concentration, pH, and mL H2O2/L PW (phenol wastewater) were chosen as effective parameters on the process. To plan an experiment and maximize phenol removal, the response surface methodology (RSM) was applied. Ideal conditions for optimum efficiency (95.96%) include initial phenol concentration of 58 mg/L, pH of 7.51, reaction time of 68.61 min, mL H2O2/L PW of 0.18, and catalyst dosage of 0.4 g/L PW. Trapping experiments prove that ˙O2 and ˙OH produced in Fenton and photocatalytic processes are the predominant active radicals in this process. The kinetics was fitted with the first‐order, second‐order, n‐order, and Langmuir–Hinshelwood models using nonlinear least squares techniques. The n‐order model with n = 0.54 was found to be the most suitable model (R2 0.998), with a model constant of k = 0.11 (mol0.46/L0.46.s). [ABSTRACT FROM AUTHOR]

The synergy of integrating semiconductors and MOF photocatalysts is the chief motive for this review paper. This merit has been combined with the microfluidic platforms, which are the cutting‐edge technology of synthesis. The microfluidic synthesis of semiconductors and MOF photocatalysts are categorized according to morphology and linker, respectively. Enhancing the effectiveness of photocatalysis comes along with adding a proper amount of electron acceptor or hole scavenger, combing electrochemical with photocatalytic degradation, and optimizing the photocatalyst band gap. Moreover, approaches for improving photocatalytic activity of MOFs can be classified as functionalization of organic linkers/metal centers, sensitization, incorporation of nanoparticles, and hybridization with semiconductors. Finally, the current applications of microfluidic devices, from the detection of water quality parameters to the elimination of water contaminants, have been addressed. [ABSTRACT FROM AUTHOR]

The aim of this study was to consider the efficiency of the electro‐Fenton process for organic compound reduction in an industrial dairy effluent. Experiments were conducted to evaluate the effect of several parameters, such as reaction time, pH, H2O2/Fe2+ molar ratio and volume fraction of H2O2 to dairy wastewater (mL/L), on the process performance. The Taguchi technique was applied to investigate the optimum operating conditions. The optimum chemical oxygen demand removal (93.24%) was experimentally obtained at a pH value of 7.58, reaction time of 87.13, current density of 58.5, H2O2/Fe2+ molar ratio of 3.62 and volume fraction of H2O2 to dairy wastewater of 1.39 mL/L.
