In this study, the synthesis of cadmium oxide (CdO) nanostructures (NSs) was carried out by utilizing the leaf extract of Dalbergia sissoo. The as-prepared CdO-NSs were analyzed via techniques of Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), X-ray diffraction analysis (XRD), and ultraviolet–visible spectroscopy (UV-VIS).

The poor stability of metal halide perovskite in water is one of the main obstacles restricting its practical application.

Cadmium (Cd) contamination of arable soils seriously threatens the safety of food products and sustainable development of agriculture. Iron/manganese oxide-based amendments have been widely applied to remediate heavy metal polluted paddy soils.

Biohydrometallurgy waste (BW) was used as sulfate sources for supersulfated cement (SSC) production with the aim of providing an alternative binder for cemented paste backfill (CPB).

Arsenic was known as human carcinogen. It was therefore of great importance to better understanding the release behavior of arsenic in soils for managing and controlling the potential risks of smelter contaminated sites.

This study investigated the release of dissolved organic matters (DOMs) from biochar under DC electric field and the roles of the released DOMs on the removal of heavy metal lead (Pb) from the soil coupled with electrokinetic (EK) remediation.

Lead smelting slag (LSS) is a hazardous waste containing heavy metals (Cr, Ni, Cu, Zn, As, and Pb) and its improper disposal may cause irreparable damage to the ecosystem. Cementitious materials prepared with LSS can be used in construction fields and hazardous heavy metals are also solidified in prepared cementitious materials.

Lithium-ion battery technology is one of the innovations gaining interest in utility-scale energy storage. However, there is a lack of scientific studies about its environmental performance. This study aims to evaluate the environmental impacts of lithium-ion batteries and conventional lead-acid batteries for stationary grid storage applications using life cycle assessment.

Although the biosynthesis of nanoparticles by microorganisms can overcome problems associated with common synthesis methods, using pathogenic bacteria, isolating NPs from the cell, and having producing agents in broth media are challenging. This research aimed to biosynthesize cadmium sulfide nanoparticles from the aqueous extract of Lactobacillus acidophilus and improve the biosynthesis process by response surface methodology.

As the different properties of conventional copper anode slime and scrap copper anode slime (SCAS), the disposal of arsenic before the extraction process is very important. There was simultaneous leaching of As and Sn when the hydrometallurgical process or the sulfation roasting-leaching was applied to treat arsenic in the SCAS. It was difficult to achieve the effective separation of arsenic and tin by these methods.

Biochar composites, as a kind of common adsorption and purification materials, are usually prepared by carbonizing biomass firstly and then loading with adsorbent. In this study, an innovative facile one-step pyrolysis-loading process was proposed to synthesize a magnetic high-loading zero-valent iron/biochar composite (BC-ZVI) directly from fresh bamboo immersed with FeCl3 solution.

The costly desulfation processes have severely restricted the development and industrial application of hydrometallurgy lead recovery process. In this work, new high efficiency and value-added desulfation method of the spent lead paste is proposed.

Cadmium pollution in river sediment is serious and single remediation method is difficult to deal with. Thus, it is extremely urgent to remediate Cd contaminated river sediments. A new remediation system with phosphate solubilizing bacteria (PSBs) and biochar supported nano-hydroxyapatite (nHAP@BC) was provided to enhance the immobilization efficiency of Cd in this research. The passivation effect of PSB + nHAP@BC under different conditions and its mechanism were investigated.

Effectively removing heavy metals from the wastewater using a green low-cost natural polymer-based adsorbent received a great deal of attention. In this study, natural γ-polyglutamic acid (γ-PGA) and ε-poly-L-lysine (ε-PL) functionalized lignin (DLGS and DLLS) were synthesized through demethylation/phenolation and amination to increase its intrinsic reactivity and adsorption sites, which were used to remove heavy metals from aqueous solutions.

Polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/F) and heavy metals emitted from hazardous waste incinerators have aroused public concern due to the risks to the environment and human health.

Many types of anionic pollutants exit in the aqueous environment including the group containing halogen (F-, I-, IO3-, BrO3-, ClO3−), the group containing heavy metals (VO43−, AsO33−, CrO42−, AsO43−), and eutrophic elements resulting from agricultural, aquacultural, urban and industrial activities (NO3−, PO43−).

Chlorine sources and heavy metal catalysts play an important role in the formation of dioxins during the incineration of mineralized refuse in landfills. Through the use of different external chlorine sources and pretreatment methods, their effects on the formation of dioxins in flue gas from mineralized refuse incineration were studied.

A three-step bipolar membrane electrodialysis (BMED) system was used to remove arsenic and cation metals from copper slag (CS) generated during the copper ore 

Energy storage deployment for stationary applications is expected to grow in the next decade, and there is a requirement for storage solutions that minimise materials demand. Soluble lead redox flow battery is a type of flow battery in the early phase of design with the potential for a lower cost than other flow battery solutions. This study presents the first cradle-to-gate life cycle assessment of the soluble lead redox flow battery.
