Enhanced remediation of cadmium-polluted soil and water using facilely prepared MnO2-coated rice husk biomass

Yutong Zhang et al.

Summary: Metal oxide-modified biochar is effective for remediation and adsorption of heavy metals in polluted soil and wastewater. This study investigated the interaction between cellulose and hemicellulose with metal oxides on the surface of biochar/biomass, as well as the loading stability, adsorption capacity, and mechanism of metal oxides. The findings suggest that the use of weakly crystalline birnessite rice husk biomass composites (MBC) can immobilize heavy metals in cadmium-polluted soil and wastewater through monolayer chemisorption, achieving a maximum adsorption capacity of 115.04 mg g-1 and reducing Cd concentration by up to 62.5%.

Stabilization of arsenic, antimony, and lead in contaminated soil with montmorillonite modified by ferrihydrite: Efficiency and mechanism

Miao Jiang et al.

Summary: This study investigates the immobilization performance of a modified montmorillonite (amFe@Mont) for As, Sb, and Pb in soil. The results show that amFe@Mont can effectively stabilize these heavy metals in the soil, with stabilization efficiencies reaching 86.28% for Sb and 94.60% for Pb after 56 days. The SBET method achieves reductions of 87.34%, 54.59%, and 17.59% for As, Sb, and Pb, respectively. The addition of amFe@Mont also improves soil properties and bacterial richness and diversity.

Hydroxyapatite and lead-substituted hydroxyapatite near-surface structures: Novel modelling of photoemission lines from X-ray photoelectron spectra

Elvis O. Lopez et al.

Summary: X-ray photoelectron spectroscopy (XPS) is a valuable tool for studying the surface characteristics of hydroxyapatite (HA) in biomedical and catalysis materials. Theoretical reconstruction and experimental analysis revealed that the binding energies in XPS spectra are significantly influenced by photo-emitters from near-surface sites and crystallographic orientation, providing insights into the complex structures of HA and lead-substituted hydroxyapatite (PbCaHA).

Response of microorganisms to phosphate nanoparticles in Pb polluted sediment: Implications of Pb bioavailability, enzyme activities and bacterial community

Jia Wan et al.

Summary: The study revealed that different types of phosphate nanoparticles (PNPs) can reduce the bioavailability of lead, influence enzyme activities, and alter bacterial community structure. Microbes responded differently to PNPs, with increases in richness and diversity. Interestingly, CMC-nClAP induced fewer changes in microbial activity and community compared to other PNPs.

Effects and Mechanisms of Copper Oxide Nanoparticles with Regard to Arsenic Availability in Soil-Rice Systems: Adsorption Behavior and Microbial Response

Qianhua Wu et al.

Summary: This study investigated the adsorption behavior of CuO NPs with regard to As in soil and the effects of CuO NPs on the microbial community in As-contaminated soil-rice systems. The results showed that CuO NPs could temporarily adsorb As in soil and high doses of CuO NPs promoted As release. CuO NPs also had significant impacts on the microbial diversity and gene abundance related to As cycling.

Iron-doped hydroxyapatite for the simultaneous remediation of lead-, cadmium- and arsenic-co-contaminated soil

Zhihui Yang et al.

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.

Dual functional sites strategies toward enhanced heavy metal remediation: Interlayer expanded Mg-Al layered double hydroxide by intercalation with L-cysteine

Danyang Wang et al.

Summary: The discharge of toxic heavy metals is a serious threat to both human health and the environment. However, current water purification systems lack effective materials for the rapid, efficient, and cost-effective remediation of these toxic heavy metals. In this study, a new adsorbent called L-cysteine (Cys) intercalated Mg-Al layered double hydroxide (MgAl-LDH/Cys) was developed for the removal of Pb(II) and Cd(II). This material has a loose lamellar porous structure and, thanks to the intercalation of Cys, it has both increased diffusion of heavy metals and additional capture sites. As a result, MgAl-LDH/Cys exhibited significantly higher sorption capacity and faster sorption kinetics compared to pristine MgAl-LDH. These findings suggest that MgAl-LDH/Cys has great potential for practical applications in heavy metal remediation.

Yan Sun et al.

Summary: A new method utilizing ball milling and sodium sulfide has been developed for efficient treatment of hexavalent chromium in soda ash Chromite Ore Processing Residue. This method significantly reduced the Cr(VI) concentration and achieved a high reduction efficiency. The results showed improved liberation of chromite grains and reduction of Cr(VI) in chromite and magnesioferrite, providing guidance for future industrial applications.

Study on the spatial distribution of ureolytic microorganisms in farmland soil around tailings with different heavy metal pollution

Xuesong Hu et al.

Summary: This study investigated urease genes in agricultural soils surrounding tailings in two dimensions: heavy metal pollution and soil depth. It showed that heavy metal concentration has a significant effect on ureolytic microorganisms, while changes in microorganisms with increasing soil depth varied based on the level of heavy metal contamination. Additionally, Proteobacteria, Actinobacteria, and Thaumarchaeota were identified as dominant phyla, but their responses to heavy metal concentrations differed.
