Summary: Electrochemical oxidation (EO) using boron-doped diamond electrodes (BDDs) was effective in treating landfill leachate (LL), with lower boron doping concentration leading to better performance. EO inactivated bacterial cells within 2 hours, possibly due to the penetration and reaction of electrogenerated oxidants. The toxicity of EO-treated LLs was lower than raw ones, suggesting that appropriate electrolysis parameters can reduce toxicity without compromising nutrient removal and disinfection capabilities, although the salinity and oxidation pathways of LLs require further investigation.

Summary: Electrochemical processes, especially when coupled with anode and cathode processes, show promise in efficient wastewater treatment. Through the study, it was found that the EC process had the highest removal efficiency, followed by E-peroxone and ECO. Coupled ECP process was more efficient than ECOP, but the synergistic effect for drilling wastewater treatment was poor, indicating that the EC process may play a dominant role. These results suggest that a single, coupled, or sequential process should be chosen based on water quality and components of the wastewater to achieve high removal efficiency.

Summary: This paper focuses on evaluating the mobility of four hexachlorocyclohexane (HCH) isomers using soil vapor extraction (SVE) combined with direct electrokinetic (EK) treatment. The results showed that SVE was highly efficient, removing nearly 70% of the four HCH isomers in the 15-day tests. Electrokinetics facilitated the transport of HCH to the cathode through various electrochemical processes, which were accurately modeled using a 1-D transport equation. Increasing the electric field resulted in enhanced pollutant transport, although 15 days was insufficient for efficient transportation of pollutants towards the cathode. The loss of water content near the cathode highlighted the need for electrokinetic flushing technologies instead of simple direct electrokinetics. Overall, no significant differences were observed in the removal of the four HCH isomers between SVE and EK processes.

Summary: This study investigates the removal of lindane using persulfate activated with ferrioxalate under simulated solar light and circumneutral pH conditions. The influence of operating parameters is evaluated, and a kinetic model based on radical mechanism is proposed and validated. Results indicate that complete removal of lindane can be achieved in 300 minutes using 2.29 mM persulfate and 0.12 mM ferrioxalate. Furthermore, chloride mineralization higher than 90% is attained under these conditions. The proposed kinetic model fits well with experimental results and can aid in predicting lindane degradation in complex effluents and different operating conditions.

Summary: This study investigates the degradation of a mixture of pharmaceutics in different types of water matrices through various methods including photolysis, electrolysis, and photo-electrolysis. A new metrological approach is developed to screen pharmaceuticals in waters, allowing for the detection at low concentrations. The results show that the inorganic composition of the water matrix has a direct impact on the efficiency of drug removal, with better degradation observed in experiments with surface water. The most recalcitrant drug studied is ibuprofen, while diclofenac and ketoprofen are found to be the easiest to degrade. Photo-electrolysis is found to be the most efficient method, although it requires higher energy consumption.

Summary: This study evaluates the influence of ultrasound (US) on the absorption and electrochemically assisted absorption of gaseous streams polluted with BTX. The experimental device combines a jet mixer absorber and a single-compartment electrochemical flow cell equipped with a BDD anode. Results show that the application of US has a positive effect on the amount of pollutants absorbed and oxidized, promoting mass transfer processes and activating oxidizing species. Intermediates produced in the oxidative degradation of BTX were mainly carboxylic acids. The removal rate increases with an increase in current density, but the elimination efficiency and the synergy coefficient decrease. A simple model is formulated and applied to satisfactorily reproduce experimental results and aid in understanding the processes involved.

Summary: Developing highly selective anode materials for hypochlorite generation in low-concentrated sodium chloride solutions is challenging. In this study, ruthenium-based binary anodes (Ti/RuO2 -Sb2O4 and Ti/RuO2 -TiO2) were synthesized using different heating methods. The anode characteristics and catalytic activity were found to be influenced by the heating method and chemical composition. The Ti/RuO2 -TiO2 anode prepared by laser heating showed the highest electrocatalytic activity for generating hypochlorite from low-concentrated NaCl solutions. This study provides new insights into the preparation of low-cost materials for efficient disinfectant generation.
