Summary: The coexistence of different metal ions affects the induction and stability of Cu-induced phosphate precipitates. While Cu-Ca coprecipitation enhances stability, Cu-Pb coprecipitation shows the opposite effect, indicating the importance of considering the influence of coexisting metal ions in immobilising heavy metals in the environment using phosphate mineralisation technology.

Summary: Chemical immobilisation is commonly used to remediate heavy metal contaminated soil, but rainfall, especially acid rain in southern China, plays an important role in the reactivation of immobilised heavy metals. Wet-dry alternations were used to simulate metal leaching by rainwater, and the distribution of Cd and Zn speciation in iron oxide-immobilised soil was investigated. The effects of wet-dry alternations on soil properties and amendments were also assessed.

Summary: Enamel demineralization, a common dental problem, is a concern for dental professionals and patients due to its impact on both health and aesthetics. Amorphous calcium phosphate (ACP) has gained attention as a potential agent for preventing or treating enamel demineralization. This article briefly reviews ACP stabilizers and their mechanisms, as well as the scientific evidence supporting the remineralization ability of these agents. The limitations of current research and future prospects for clinical translation of ACP agents are also discussed.

Summary: Adsorbents such as carbon-based materials, metal oxides, and metal-organic framework composites have been studied for their ability to remove toxic heavy metal ions from wastewater and water. However, these adsorbents have their own limitations. This research aims to develop a new adsorbent based on a polymer nanocomposite made of resorcinol-formaldehyde aerogel and hydroxyapatite nanoparticles. The results showed that the RF aerogels with HA nanoparticles were highly effective in adsorbing heavy metal ions from aqueous solutions, and the adsorption capacity increased with contact time.

Summary: Adsorbent materials based on titania and phosphate show great promise for heavy metal remediation in acidic sulfate environments, with successful functionalization depending on the phase of titania used and the structure of the phosphate ligand. Realistic conditions testing is essential for understanding the impact of counterions on heavy metal speciation and binding. Increasing the porosity of the titania framework enhances heavy metal removal while maintaining selectivity for toxic heavy metals.

Summary: In this study, MgO-loaded fish scale biochar (MgO-FB) was synthesized and used for the adsorption of aquatic Cu2+, Cd2+, and Pb2+ as well as the immobilization of heavy metals in soils. The results showed that MgO-FB had excellent adsorption capacities for Cu2+, Cd2+, and Pb2+ and could maintain this capacity under various environmental disturbances. The enhanced adsorption capacity was attributed to the hydroxyapatite components and the MgO micro-nanoparticles on MgO-FB, as well as the coordination and complexation with different functional groups. MgO-FB also effectively reduced the contents of available Cu, Cd, and Pb in soils. In conclusion, MgO-FB has great potential for the remediation of heavy metal contaminated waters and soils.

Summary: The solar steam generation method was used to treat the acidic wastewater containing lead ions from car battery recycling plants. A light porous ceramic substrate (PCS) was prepared using clay, human hair, and nano-hydroxyapatite. The physical and chemical characteristics of the PCS were identified through various techniques. The PCS exhibited high porosity due to the removal of human hair during calcination and had the ability to quickly pump water molecules to its surface through the microchannels of nano-hydroxyapatite. The PCSs showed promising results in wastewater treatment on both laboratory and semi-industrial scales, with efficient evaporation and thermal conversion.

Summary: Seawater mining is a green alternative for obtaining minerals, as seawater is a renewable and abundant resource. The Critical Raw Materials (CRM) list has been created by the European Union due to the lack of ways to obtain certain raw materials. Although seawater contains almost all elements, only a few economically feasible ones can be extracted. Saltwork brines, which are naturally concentrated compared to seawater, can make the extraction and recovery of Trace Elements (TEs) easier. Polymeric and inorganic sorbents have been evaluated for TEs recovery from synthetic brines, and selective carboxylic, phosphonic/phosphinic, and amine sorbents have shown promising sorption and recovery capabilities for certain TEs.

Summary: Nitrogen is an essential macronutrient for improving agricultural yields, but its excessive use in fertilisation and presence in wastewater and sludge lead to emissions and eutrophication. The Haber-Bosch process is the main method for nitrogen production, but it is energy-intensive and relies heavily on imports. Sustainable alternatives and efficient management schemes are necessary to address these issues.

Summary: The availability of raw mineral resources containing elements included in the Critical Raw Materials (CRMs) list is a growing concern for the European Union. Sea mining, particularly the extraction of brines obtained in solar saltworks, has shown promise as a secondary source of valuable CRMs. However, the low concentration of some elements in the brines presents challenges in developing sustainable and economically feasible recovery routes. This study investigates the recovery of Trace Elements (TEs) from saltworks brines after ion exchange processes, demonstrating successful recovery of targeted elements except for Ge(IV), which requires further evaluation of alternative routes due to the limitations of current precipitation methods.

Summary: Magnesium has been recognized as a critical raw material by the EU, and there is a growing interest in finding sustainable sources of Mg2+ to meet the demand and reduce mineral ore consumption. Saltwork bitterns, the by-products of solar sea salt production, have gained attention due to their high Mg2+ concentrations and low content of Ca2+ and bicarbonate. This study investigates the possibility of extracting highly pure magnesium hydroxide powders from bitterns, demonstrating the potential for water valorization and resource recovery.

A selective precipitation process was developed to recover antimony and bismuth from the eluate, considering the presence of high contents of As(V). Treatment with SO2(g) or NaHSO3(s) was used to reduce As(V) and Sb(V) before obtaining antimony oxychloride (Sb4O5Cl2) and bismuth oxychloride (BiOCl) with high purity using appropriate pH control.

Summary: This study compares the potential of four different polymer-stabilized nano zero-valent iron (nZVI) in removing nitrate (NO-3) from groundwater and assesses the effect of combined supplementation of polymer-stabilized nZVI and acetate on NO-3 reduction. The results show that Tween80-stabilized nZVI outperforms other polymer-stabilized nZVI in removing NO-3 from water. Coupling Tween80-coated nZVI and acetate enhances both the overall NO-3 removal and the conversion of reduced NO-3 to N2(g). This study demonstrates the potential of Tween80-stabilized nZVI in remediating NO-3-contaminated groundwater.
