Summary: This study investigated the advanced oxidation technology of ozone and ferrate (ozone/Fe (VI)) for the degradation of micropollutants. The results showed that ozone/Fe(VI) process efficiently degraded sulfamethoxazole (SMX) and diclofenac sodium (DCF), with higher degradation efficiency under acidic conditions. Scavenging and probe experiments identified ozone, Fe(VI), OH, and Fe(IV)/Fe(V) species as the main oxidants for SMX and DCF degradation. The study also identified the transformation products of SMX and DCF and evaluated their ecotoxicity. These findings have important implications for water treatment using the ozone/Fe(VI) process.

Summary: The study demonstrates that Fe(VI) can efficiently remove 4-CP in water treatment, with optimal degradation occurring at pH 9.20 and complete degradation of 4-CP achieved at a 5:1 mole ratio. The reaction rate of Fe(VI) with 4-CP is pH-dependent, with the rate-determining step being the reaction between deprotonated Fe(VI) and deprotonated 4-CP.

Summary: The generation of Cr intermediates and their oxidizability in the photocatalytic conversion of Cr(VI) and organic contaminants were emphasized in this study. It was found that the reduction of Cr(VI) indeed promotes the photodegradation of bisphenol A (BPA). The presence of the Cr(V) intermediate was confirmed through electron paramagnetic resonance analysis, and its oxidation played a crucial role in the degradation of BPA. Density functional theory calculations showed that photogenerated electrons can facilitate the conversion of Cr(VI) to Cr(V), which contributes to the subsequent oxidation step for BPA degradation.

Summary: The traditional Fe(VI) treatment process does not fully utilize fresh iron flocs. This study proposes a novel Fe(VI) flocs recycling process, where the flocs are recycled into the front-end reactor and further react with Fe(VI). Compared to Fe(VI) alone, the CODCr and TP of hospital wastewater decreased when treated with Fe(VI) flocs recycling process. However, the removal of NH3-N and TOC was limited. Moreover, the Fe(VI) flocs recycling process showed the best performance in purifying wastewater compared to polymeric ferric chloride and ferric chloride.

Summary: The complexation of tetracyclines with Fe species plays a significant role in the removal of tetracyclines by ferrate. Experimental results show that the complexation of tetracyclines with Fe3+ contributes to 79% of the overall removal, followed by oxidation (11%) and adsorption/flocculation (10%). Thermodynamic and kinetic calculations suggest that complexation reactions between Fe3+ and tetracyclines are more likely to occur than oxidation reactions between ferrate and hydroxyl radicals. The complexation rates of tetracyclines with Fe3+ determine the removal of multiple tetracyclines by ferrate, highlighting the importance of considering complexation in the removal of pollutants.

Summary: In this study, the biodegradability of 4-NP and its degradation products in the presence of ferrate(VI) were evaluated. It was found that 4-NP was not completely mineralized and formed degradation products when ferrate(VI) was added. Mass spectra analysis revealed a unique peak at m/z 223 for the degradation products of 4-NP with Fe(VI). Furthermore, the estrogenic activity of 4-NP in aqueous solution was significantly reduced with increasing Fe(VI) concentration.

Summary: This study investigated a control strategy for spore-forming bacteria (SFB) in drinking water treatment. The results showed that pre-oxidation, coagulation sedimentation, and UV-AOPs inactivation were effective in transforming, removing, and inactivating SFB spores. The study also demonstrated the enhanced inactivation of the most chlorine-resistant SFB strain by adding chemicals to the UV irradiation process. The findings provide valuable references for dealing with SFB outbreak risk in drinking water treatment.

Summary: The discharge of widely used fluorinated aromatics (FAs) leads to their notoriously high persistence and toxicity in natural environments. Defluorination is the key step for FAs pollutants detoxification. In this study, 4-fluorophenol (4-FP) was selected as a model compound to optimize the electrochemical hydrodefluorination (HDF) process and understand the reaction mechanism. The investigation showed that Rh coating outperformed Pd coating due to its higher reactivity towards C-F bond cleavage.

Summary: This study focused on the semihydrogenation of acetylene in an ethylene-rich stream using two alloyed Pt catalysts PtCu and PtCo. The PtCu catalyst showed higher activity and ethylene yield compared to PtCo due to its higher unoccupied Pt d-orbital density. This indicates that alloying Pt with Cu is more promising for industrial relevant SHA catalyst.

Summary: This work presents a continuous solvent extraction method for the separation of cobalt and nickel in a millifluidic system using Cyphos IL 101 (C101) as the extractant. The optimal conditions for extraction performance and solvent properties were determined by investigating the effects of channel length, flow rate, and temperature. The performance of a developed manifold structure was compared to a single-channel system, and excellent separation results were achieved. The continuous separation process using the manifold structure resulted in high purity cobalt and nickel products.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
