Heavy metal pollution has increasingly affected human life, and the treatment of heavy metal
pollution, especially chromium pollution, is still a major problem in the field of environmental …

The traditional synthesis of iron nanoparticles has the problems of high cost and secondary
pollution. There is an urgent need for an economic, effective and environment-friendly …

Remediation of Cr (VI) pollution by nanoscale zero-valent iron-loaded biochar (nZVI-BC) is a
hot research topic at present. However, the interaction of natural organic matter (NOM) and …

Geopolymer binders can be used as a sustainable alternative to Portland cement. Despite
the extensive research regarding the influence of different parameters on the properties of …

Geopolymers, as a kind of inorganic polymer, possess excellent properties and have been
broadly studied for the stabilization/solidification (S/S) of hazardous pollutants. Even though …

The improper disposal of solid wastes could bring great pressures and threats to ecosystem.
These detrimental impacts could be reduced or eliminated through solidification/stabilisation …

Chromium slag is a hazardous solid waste, and its safe disposal and utilization are of great
significance to the environment. In this study, the geopolymer containing more than 50 wt …

Biochar-supported nanoscale zero-valent iron (nZVI) has been unitized for the reduction of
Cr (VI). However, the low specific surface area of biochar and the surface oxidation of nZVI …

Among the toxic metals, hexavalent chromium [Cr (VI)] has attracted much attention due to
its high mobility and toxicity, rendering considerable challenges for long-term remediation. In …
