Glass is used as a protective cover, diminishing the material′sĬapability to absorb UV radiation. Their reflective capacity is poor for wavelengths between 300 andĤ00 nm during the manufacturing process of these mirrors, common Preferred for their high reflectivity in the visible spectrum, although Among some of the materials used, silver mirrors are Material characteristics to optimize the UV radiation that irradiates UV radiation in a photoreactor design, it is vital to consider various It is necessary to use materials that allow a high reflectance of However, the main disadvantageĪdditionally, to maximize the yield of the photocatalysis reaction, To common glass, borosilicate glass (Pyrex) has a higher transmittanceĪt wavelengths between 300 and 400 nm. Glass, but its efficiency depends on the type of glass that is used.įor example, common glass has a variable iron concentration in itsĬomposition, allowing different grades of UV light absorption. The most common material in photoreactor design and construction is Thickness, thus decreasing the transmittance of UV rays. Material, it is necessary to increase the photoreactor’s wall 4 However, the main issue with fluoropolymers (FP) and glass, which allow a high transmittance of UV rays to the With specific optic characteristics, such as a high transmittanceĪnd reflectance, using mostly clear materials, such as fluoropolymers Now, photocatalysis reactions require reactors Which can carry out the degradation of organic compounds that areĭifficult to eliminate via traditional wastewater treatment methods. Light to produce highly reactive oxygen species (e.g., hydroxyl radicals),
1, 2 In this process, a semiconductor material is irradiated with UV Heterogeneous photocatalysis is considered as one of the researchĪreas among advanced oxidation processes of greater interest. The reactor depending on the stirring rate of the reactor. Simulation, which showed the theoretical trajectory of particles inside Rpm was verified using a COMSOL Multiphysics computer fluid dynamics Of TiO 2 particles inside the reactor when stirred at 475 Finally, the homogeneity in the distribution Parameters were determined and found to be similar to those found Stirring speed (RPM), UV lamps, and temperature) over the photocatalysis Parameters (such as the catalyst mass (TiO 2 Degussa P-25), On the other hand, the effects of different Source to build the photoreactor, a dry gel nail lamp was used withĩ W, λ = 365 nm bulbs. Pyrex glass was the most suitable material to work with. Types of glass were evaluated with the objective of finding a functionalĪnd economic material to build the photoreactor.
Additionally, during the building process, different
Reaction efficiency obtained through this research with results from Phenol concentration was used as the reference to compare the photocatalysis And optimized to carry out the degradation of phenol.
