Summary: Direct current (DC) electrocoagulation is effective in decolorizing indigo dyeing wastewater but has low chemical oxygen demand (COD) removal rate and high energy consumption due to electrode corrosion. To improve COD removal rate and reduce energy consumption, a peroxi-alternating current (AC) electrocoagulation (EC) system was developed. The study focused on the effects of power type, electrode combination, and process parameters on COD removal rate and decolorization rate, and investigated the COD degradation mechanism. Results showed that AC electrocoagulation enhanced floc adsorption capacity and achieved a COD removal rate of 51.19%. The coupled peroxi-AC electrocoagulation system further removed sulfite and residual dyes, reaching COD removal and decolorization rates of 78.09% and 98.47%, respectively. The system also had significantly lower energy consumption compared to DC electrocoagulation, with a reduction of 70%. Overall, the peroxi-AC EC system is an effective method for reducing COD concentration in indigo dyeing wastewater.

Summary: The construction of a heterojunction and the introduction of a cocatalyst can enhance the photocatalytic efficiency by promoting the transfer of photogenerated electrons. In this study, a ternary RGO/g-C3N4/LaCO3OH composite was synthesized by constructing a g-C3N4/LaCO3OH heterojunction and introducing a non-noble metal cocatalyst RGO. The visible light photocatalytic activity of the ternary composite was significantly improved due to its enhanced visible light absorption capability, reduced charge transfer resistance, and facilitated photogenerated carrier separation.

Summary: The present study demonstrates a simple and effective sol-gel doping method that can engineer the band-gap of TiO2 nanoparticles at low temperature. Different dopants (N, C, Ag, and Fe) were used to decrease the band-gap energies from UV range to visible range. The structural and functional properties of the doped nanoparticles were controlled by the composition of dopants and precursors, resulting in improved adsorption properties and high specific surface area. Photocatalytic experiments confirmed the enhanced degradation of methylene blue and acid pink dye under visible light irradiation, with nitrogen-doped TiO2 and iron-doped TiO2 showing the highest degradation rates. XRD analysis revealed that the doped TiO2 nanoparticles achieved anatase structure at a lower temperature compared to previous studies.

Summary: This study investigates the control of NO in marine ship exhaust and proposes a new method for NO2 removal based on hydrodynamic cavitation. The results show that hydrodynamic cavitation can delay but not prevent the production of NO, and the accumulation and decomposition of HNO2 are the primary causes of NO formation. Further experiments reveal that ClO2, H2O2, and Na2S2O8 can slightly increase the NO2 removal efficiency, while NaClO2 is less effective than water.

Summary: In this study, a plain strategy for fabrication of a novel composite ZnO/CuCo2O4 was designed, and it was applied as a catalyst for peroxymonosulfate (PMS) activation to decompose enrofloxacin (ENR) under simulated sunlight. The results showed that the ZnO/CuCo2O4 composite could significantly activate PMS under simulated sunlight, leading to the generation of more active radicals for ENR degradation. The study also evaluated the influences of various experimental factors on ENR degradation and proposed several reasonable ENR degradation pathways. The novel strategy provided by this study integrates state-of-the-art material science and advanced oxidation technology for wastewater treatment and environmental remediation.

Summary: This study explores the use of N-doped graphdiyne nanotubes (NGNTs) as a catalyst for metal-free PMS activation in water remediation. The NGNT-PMS system decomposes heterocyclic contaminants via electron-transfer-mediated nonradical oxidation, where metastable NGNT-PMS* complexes act as the primary oxidants. The NGNT-PMS system exhibits higher reaction rates compared to N-doped carbon nanotubes (NCNTs) and graphene oxide (NGO) systems, and also plays a crucial role in the cleavage of pyridine heterocycles and C-Cl bonds.

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.
