Mercury contamination in soil, water and air is associated with potential toxicity to humans and ecosystems. Industrial activities such as coal combustion have led to increased mercury (Hg) concentrations in different environmental media. This review critically evaluates recent developments in technological approaches for the remediation of Hg cont...

This paper describes a novel approach for enhancing membrane technology for the removal of heavy metal cations in contaminated waters. A simple method of forming a positively charged polyamide (PA) nanofiltration (NF) membrane has been developed by attaching a layer of hyperbranched polyethylenimine (PEI) to the PA surface, involving the linking of...

The present work reports a sustainable adsorption-reduction strategy for disposal of Cr(VI)-bearing wastes. By cross-linking between boehmite and chitosan to prepare amino-functionalized boehmite adsorbents, Cr(VI) could be adsorbed from the Cr(VI)-containing solutions by the adsorbents with the maximum adsorption capacity of 120.2 mg/g, which was ...

Three kinds of CeO2 materials with different morphologies (nanorods, octahedron and nanocube) were prepared by simple hydrothermal method. Adsorption behaviors of fluoride onto the three CeO2 materials were investigated. Three CeO2 materials exhibited different adsorption performance for fluoride. The CeO2 nanorods mainly exposed {1 0 0} and {1 1 ...

A direct approach was presented to graft phosphonate groups on magnetic mesoporous carbon by an impregnation method with environmentally friendly precursors unlike the conventional methods involving a series of complicated steps and harsh conditions. Through the in situ reduction of Fe3+, magnetite particles of similar to 10 nm were successfully em...

The chromium-based metal organic framework MIL-101(Cr) served as a host for the in situ synthesis of Fe3O4 nano particles. This hybrid nanomaterial was tested as an adsorbent for arsenite and arsenate species in groundwater and surface water and showed excellent affinity towards As-III and As-V species. The adsorption capacities of 121.5 and 80.0 m...

In this study, a method combined low-field magnetic separation (MS) with flotation, named as gas-assisted magnetic separation (GAMS), was applied for the removal of cadmium from wastewater. With bubbles' assistance, the speed of magnetic separation can be greatly improved and the limitation of magnetic force on the capture distance can be overcome....

Hyperbranched polymers or/and graphene oxide nanosheets were used to synthesize poly(acrylic acid)-based hybrid hydrogels with high water absorption ability, excellent mechanical properties, and environmental remediation abilities through a novel one-step, cost-effective, and environmentally friendly method. The combination of hyperbranched polymer...
