“…The individual microspheres in the u_20 sample also show an improved performance compared to the fused spheres in the u_10 sample, which could be attributed to the higher surface area-to-volume ratio and shorter mass transport lengths of the individual microspheres. 50,51…”

A four stage semi-pilot scale RFR reactor with ceramic disks as support for TiO2 modified with silver particles was developed for the removal of organic pollutants. The design presented in this article is an adaptation of the rotating biological reactors (RBR) and its coupling with the modified catalyst provides additional advantages to designs where a catalyst in suspension is used. The optimal parameter of rotation was 54 rpm and the submerged surface of the disks offer a total contact area of 387 M2. The modified solid showed a decrease in the value of its bandgap compared to commercial titanium. The system has a semi-automatic operation with a maximum reaction time of 50 h. Photo-activity tests show high conversion rates at low concentrations. The results conform to the Langmuir heterogeneous catalysis model.

“…Moreover, in the mentioned study (Mashayekh-Salehi et al, 2017), the maximum ACT mineralization for O 3 /MgO process was found 94% at a reaction time of 30 min. In another study, Lin et al (Lin et al, 2016) have studied the ACT degradation by the UV/TiO 2 process. According to their findings, the sole UV process removed only 12% of ACT, however when combined with TiO 2 (UV/ TiO 2 process), it removed 94% of the ACT.…”

“…These findings are in accordance with the catalytic activity experiments of these preparations. It has been demonstrated that the catalytic performance of a certain catalyst depends on its specific surface area (Pocostales et al, 2011;Lin et al, 2016). A high specific surface area can provide more available sites for generation of reaction species.…”

A novel sol-gel method was employed in this study to efficiently synthesize SnO 2 nanoparticles to catalyze the ozonation of acetaminophen (ACT) from aqueous solutions. The influence of various parameters including Sn source, type of capping and alkaline agents, and calcination temperature on the catalytic activity of the SnO 2 preparations was investigated. The SnO 2 nanoparticles prepared by tin tetrachloride as Sn source, NaOH as gelatin agent, CTAB as capping agent and at calcination temperature of 550 • C (SnNaC-550) exhibited the maximum performance in the catalysis of ACT. The optimized catalyst (SnNaC-550) had spherical-homogeneous and cubic-shaped nanocrystalline particles with 5.5 nm mean particle size and a BET surface area of 81 m 2 /g, which resulted in 98% degradation and 84% mineralization of 50 mg/L ACT at 20 and 30 min reaction time, respectively when combined with ozonation (COP). Based on the radical scavenger experiments, • OH was the major oxidizing agent involved in the removal of ACT. LC/MS analysis showed that short-chain carboxylic acids were the main intermediates. Furthermore, the SnNaC-550 catalytic activity was preserved after four successive cycles. Collectively, the new method has the potential to efficiently synthesize stable and reusable SnO 2 nanoparticles to catalyze the ozonation of ACT from aquatic environments.
