Over the years, promising results have been demonstrated using various biomass-based
adsorbents for the treatment of wastewater. However, the circular economy prospect of these …

Chromium (Cr) affects human health if it accumulates in organs to elevated concentrations.
The toxicity risk of Cr in the ecosphere depends upon the dominant Cr species and their …

Reckless release of contaminants into the environment causes pollution in various aquatic
systems on a global scale. Biochar is potentially an inexpensive and environmentally …

While the potential of biochar (BC) to immobilize potentially toxic elements (PTEs) in
contaminated soils has been studied and reviewed, no review has focused on the potential …

Although magnetic modification has potential for preparing recyclable biochar, the traditional
preparation methods of loading magnetic materials on biochar will probably lead to pore …

The dense surface passivation layer on zero-valent iron (ZVI) restricts its efficiency for water
decontamination, causing a poor economy and waste of resources. Herein, we found that …

The global exponential rise in greenhouse gas (GHG) emissions over the last few decades
has triggered an urgent need to contextualize low-cost and evergreen technologies for …

Nano-biochar, characterized by its environmentally friendly nature and unique
nanostructure, offers a promising avenue for sustainable carbon materials. With its small …

In recent years, iron/biochar composite materials have been developed and efficiently used
for pollutant removal in environmental matrices due to their excellent capability of absorbing …

Abstract Hexavalent chromium (Cr (VI)) is carcinogenic and widely presented in soil. In this
study, modified zero-valent iron (ZVI) with oxalic acid on biochar (OA-ZVI/BC) was prepared …
