Summary: In this study, the steady-state concentration and lifetime of plasma-produced hydroxyl radicals in water solutions at pH 3 and 7 were quantified for the first time, along with discussions on their reactivity with other plasma-generated species. The use of chemical probes to quantify short-lived reactive species was shown to have an influence on the results and should be taken into account.

Summary: In this study, a MnO2/CeO2 composite catalyst was directly electrodeposited on corona discharge anode to form a catalytic film, achieving effective coupling of plasma and catalyst. The complexity of the equipment was reduced and the high efficiency of toluene cracking was ensured. The oxygen concentration was found to improve the catalytic activity but reduce the corona discharge plasma intensity. The best cracked rate of toluene was achieved when the oxygen content was 5.5% and the voltage was 12 kV.

Summary: Non-thermal plasma (NTP) is a promising tool for inhibiting bacterial, viral, and fungal diseases. Two types of NTP sources based on cometary and point-to-ring discharges were studied and compared. The cometary discharge is less stable but forms smaller and rapidly emerging inhibition zones, while the point-to-ring discharge is more stable but provides larger affected but often not completely inhibited zones.

By preoxidizing iodide to triiodide, iodide was successfully recovered. EDTA-2Na was used as the draw solute for its low reverse salt flux and membrane distillation was shown to achieve over 99% recovery for the draw solutes with simultaneous recovery of water.

Summary: In this study, adsorptive separation of Pb(II) from aqueous solution containing Pb(II) and other heavy metals was investigated using three adsorbents. It was found that the iminodiacetic acid-chelating resin had the highest adsorption ability, while goethite and magnetite showed selectivity for certain metal ions. The kinetics of adsorption was determined to be pseudo-second-order, with magnetite having the fastest adsorption kinetics.

Summary: Co-culture of microalgae-activated sludge has the potential to purify wastewater while reducing energy demand from aeration. This study used a mechanically stirred membrane photobioreactor to evaluate the impact of biomass retention time on treatment performance and membrane fouling. Results showed that the highest productivity was achieved at a biomass retention time of 7 days, with a lower retention time leading to increased fouling rates. The optimum biomass retention time of 7 days allowed for sufficient access to light and nutrient exchange for mutualistic interactions between microalgae and activated sludge.
