Summary: This study investigated the remediation of arsenic-contaminated abandoned mine soils. Oxalic acid was found to be the most effective washing reagent. Washing reduced the leachability and bioaccessibility of arsenic and iron in the treated soil, but it still exceeded the remediation criteria. Soil washing and subsequent solidification/stabilization could be an alternative option for remediating extremely contaminated abandoned mine soils.

Summary: The removal of NH4+, NO3-, and NH3- from wastewater can be challenging, but this study proposes a new approach using a highly biodegradable biosurfactant generated from yeast to enhance nutrient removal efficiency. The use of micellar-enhanced ultrafiltration (MEUF) reduces costs and improves ion removal compared to other methods like reverse osmosis and nanofiltration. Experimental evaluations showed that the biosurfactant achieved high removal rates for PO43-, NO3-, and NH4+ ions, and the contaminants were effectively eliminated in the permeate.

Summary: Long-term accumulation of heavy metals in paddy soils caused by acid mine drainage (AMD) irrigation poses a severe threat to environmental health. This study investigates the retention and mobility mechanisms of Cu and Cd in soil after AMD flooding, and finds that Cd is more mobile than Cu and the soil has a greater adsorption capacity for Cu.

Summary: This study explores the use of highly active silicon modified tailings (HAST) as sorbents and passivators to address the environmental risks of lead-zinc tailings. The results show that HAST has high stability and adsorption capacity, particularly for Cd ions. The main mechanisms for Cd adsorption onto HAST are ion exchange, complexation, precipitation, and electrostatic interaction. Additionally, HAST can facilitate the conversion of exchangeable Cd fractions into stable fractions in soil. Overall, this study provides a practical strategy for recycling lead-zinc tailings and treating wastewater and soil.

Summary: This study used zero valent iron (Fe-0) for in-situ remediation of contaminated soil. The results showed that Fe-0 treatment reduced the levels of Cd and Zn in the soil and increased the biomass of soybean and rape. The separated iron-rich substances adsorbed Cd and Zn and generated new iron oxides. This study suggests the feasibility of Fe-0 for soil remediation, and the use of retrievable materials from soil for permanent pollutant removal should be considered in future remediation practices.

Summary: Soil washing using FeCl3 was effective in reducing heavy metal concentrations, particularly for Pb, with the lowest concentrations achieved with a 1 M FeCl3 washing solution. However, the reduction in Cu and Zn was limited due to their initial concentrations being below regulatory standards. Sequential extraction results showed significant reductions in exchangeable and weak acid-soluble fractions of Pb upon FeCl3 washing.

Summary: In this study, a novel iron-doped hydroxyapatite composite (Fe-HAP) was developed for the simultaneous remediation of lead-, cadmium-, and arsenic-co-contaminated soil. Fe-HAP exhibited immobilization efficiencies of 79.77%, 51.3%, and 37.5% for Pb, Cd, and As, respectively. The adsorption kinetics of Pb, Cd, and As on Fe-HAP followed a pseudo-second-order model, indicating chemisorption control. XRD, SEM, and XPS analysis confirmed the formation of stable minerals between Fe-HAP and Pb, Cd, and As. Overall, Fe-HAP showed promising potential for the remediation of co-contaminated soil.

Summary: Standardized cultivation systems are important for reproducible agronomic techniques. Stone wool-based cultivation is commonly used and provides a controllable root-zone environment. This study focused on the effect of stone wool cover incision on environmental variations and tomato plant productivity. Different levels of drainage performances were created using a cover incision method, and it was found that the slabs with the lowest drainage performance had higher fruit yield than those with favorable drainage conditions. The correlation between air temperature and root-zone temperature was also affected by manipulating the cover incision process.

Summary: In this study, PVDF-based anion-exchange membranes were designed to selectively separate nitrate from chloride. Experimental data showed that increasing the concentration of PVDF enhanced nitrate transport but also increased the membrane electrical resistance. The selectivity of nitrate was found to be independent of the membrane thickness and mainly driven by the increased affinity between the anion and the membrane.

Summary: This study focuses on the modification of a commercially available polyamide thin-film composite membrane with a zwitterionic material to enhance its fouling resistance. The modified membrane shows improved salt rejection and reduced permeability compared to the pristine membrane. Fouling tests demonstrate that the modified membrane has a lower fouling ratio and higher recovery ratio. The enhanced antifouling characteristics are attributed to the improved hydrophilicity resulting from the zwitterionic brushes and the salting-in effect.

Summary: A transmembrane electro-chemisorption system with authigenic acid and base was developed for enhancing ammonia recovery from strong ammonia wastewater. The system efficiently transformed ammonium into free ammonia, which was then adsorbed and recovered through transmembrane chemisorption. This system yielded pure (NH4)2SO4 product and produced valuable byproducts of pure hydrogen and oxygen. Higher applied voltage resulted in better ammonia recovery.

Summary: To meet the huge demand for lithium resources, there is an urgent need to develop a new efficient technology for lithium recovery from salt-lake brines. In this study, a selective membrane capacitive deionization system is reported, which achieves high lithium recovery capacity and rate through the use of materials with efficient intercalated pseudo-capacitance and a high specific area porous carbon. The use of a modified thin-coated membrane allows for selective Li+ recovery, and adjusting the concentrations of Li+ and Mg2+ in the feed solution enables higher Li+/Mg2+ selectivity.
