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

The difficulty of separating the powdered biochar from the environmental medium may lead
to secondary pollution and hinder the large-scale application of biochar as an adsorbent. An …

Biochar has triggered a black gold rush in environmental studies as a carbon-rich material
with well-developed porous structure and tunable functionality. While much attention has …

Tetracycline (TC) adsorption capacity on pristine biochar was limited. Biochar modification
can greatly improve its adsorption amount. In this study, rice straw was mixed with FeCl 3 …

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

Biochar has become a popular research topic in sustainable chemistry for use both in
agriculture and pollution abatement. To enhance aqueous Cr (VI), Pb (II) and Cd (II) removal …

The presence of refractory organic pollutants (ROPs) in the ecosystem is a serious concern
because of their impact on environmental constituents as well as their known or suspected …

Biochar, due to its ability to remediate heavy metals and organic contaminants from polluted
water is considered as an economic adsorption material. This work involved pyrolysis driven …

In current era, the presence of chromium in aquatic environment are increasing diversely
due to evolution activities. Chromium exist in various oxidation state and among them …

In this study, a sugarcane bagasse biochar/nano-iron oxide composite was prepared via a
one-pot pyrolysis method by using the sugarcane bagasse-based solid waste and …
