Biochar and biochar-based materials have been studied extensively in multidisciplinary
areas because of their outstanding physicochemical properties. In this review article, biochar …

Abstract Hexavalent chromium (Cr (VI)) contamination has gained interest from regulatory
authorities due to its high toxicity and carcinogenicity. Different approaches have been …

The rapid industrial and agricultural expansion is arousing increasingly severe heavy metal
ion pollution due to their high toxicity to human beings and detrimental effect on the …

As the first of its kind, a novel biochar/iron oxide composite (BM-Fe-HC) was successfully
prepared by simply ball milling iron-laden biochar (Fe-HC). The performance and …

In recent years, magnetic biochar has been widely used in removal of pollutants from water.
In this paper, the preparation technologies of magnetic biochar are analyzed, and the …

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

With the rapid growth of new-energy batteries and metallurgical industry, water pollution
caused by toxic heavy-metals from these sectors has increased to a new level, which is …

The contamination of natural resources by hexavalent chromium (Cr (VI)) originating from
natural and anthropogenic activities is a serious environmental concern. Although many …

The magnetic covalent organic framework with β-ketoenamine linkage (Fe 3 O 4@ COF
(TpPa-1)) was fabricated by the hydrothermal method. The obtained Fe 3 O 4@ TpPa-1 …

The purpose of this study was to fabricate a chitosan modified magnetic bamboo biochar
(CMBB) for Cr (VI) detoxification from aqueous solution. Results showed that chitosan …
