Background With rapid development in agriculture and industry, water polluted with heavy
metallic ions has come to be a serious problem. Adsorption-based methods are simple …

Abstract Hexavalent chromium (Cr (VI)) is a widespread, toxic contaminant in the
environment. Owing to the increasingly strict requirements for green production and …

Electrokinetic remediation (EKR) technology is a promising method to remove heavy metals
from low permeability soil, because it is environmentally friendly, efficient and economical …

Carboxymethyl cellulose/polyethylenimine hydrogel (CMC/PEI) was firstly prepared with a
facile one-step method to enhance Cr (VI) removal. The sufficient hydrogen ions in double …

The conversion of highly toxic heavy metal hexavalent chromium (Cr (VI)) in the natural
environment into low-toxic trivalent chromium (Cr (III)) is one of the research topics of great …

Coprecipitation of Fe/Cr hydroxides with natural organic matter (NOM) is an important
pathway for Cr immobilization. However, the role of NOM in coprecipitation is still …

Microorganisms can oxidize Mn (II) to biogenic Mn oxides (BioMnOx), through enzyme-
mediated processes and non-enzyme-mediated processes, which are generally considered …

Cr (VI) released into the environment inevitably co-exists with other contaminants, such as
heavy metal ions, thus altering the performance of bacteria for Cr (VI) reduction; however …

Various remediation strategies have been developed to eliminate soil chromium (Cr)
contamination which challenges the ecosystem and human health, and chemical …

Iron hydroxides are important scavengers for dissolved chromium (Cr) via coprecipitation
processes; however, the influences of organic matter (OM) on Cr sequestration in Fe/Cr-OM …
