Chromium originates from geogenic and extensive anthropogenic activities and significantly
impacts natural ecosystems and human health. Various methods have been applied to …

Biochar (BC) has gained attention for removal of toxic elements (TEs) from aqueous media;
however, pristine biochar often exhibits low adsorption capability. Thus, various modification …

Biodegradable polymers, biochars and metal organic frameworks (MOFs) have manifested
as top prospects for elimination of harmful pollutants. In the current study, Ti-MOF was …

Heavy metals pollution has become a severe threat to human health and a challenging
problem. Nano zero-valent iron (nZVI) has a unique core-shell structure. The core Fe 0 has …

Over the past decade, biochar-supported nZVI composites (nZVI/biochar) have been
developed and applied to treat various pollutants due to their excellent physical and …

In this paper, a novel polyethyleneimine (PEI) surface-modified hydrochar (HTC) loaded
nanoscale zero-valent iron (nZVI) adsorbent (HTCTSIP-5) was developed. HTCTSIP-5 …

The lignin-based magnetic biochar (LMB) was fabricated with a facile one-step solvothermal
method. The spherical Fe 3 O 4 was successfully loaded on the lignin-based biochar. LMB …

The potential risk of various contaminants in water has recently attracted public attention.
Biochars and modified biochars have been widely developed for environmental …

Sulfidation of nano-zero valent iron (nZVI) has attracted extensive attention because it can
improve the reactivity of nZVI. Here, a type of catalyst, biochar supported sulfurized nZVI (S …

Effective purification of arsenic (As)-contaminated soil and water remains an urgent task for
mankind. Biochar was applied to remove As due to its low price, easy preparation, and high …
