In the context of climate change and the circular economy, biochar has recently found many
applications in various sectors as a versatile and recycled material. Here, we review …

Abstract Cadmium (Cd) and lead (Pb) contaminations are disturbing environmental issues,
which cause serious harm to aqueous systems and human health. Therefore, removing …

Microplastics (MPs) derived from plastic wastes have attracted wide attention throughout the
world due to the wide distribution, easy transition, and potential threats to organisms. This …

The purpose of this research was to improve the sorption ability of Pb and Cd by promoting
the ion exchange and precipitation capacity of biochar. The adsorption performance and …

Mg/Fe bimetallic oxide-modified biochar (Fe/Mg-BC) derived from Eupatorium adenophorum
was prepared by the co-pyrolysis of magnesium nitrate and ferric chloride for Pb (II) and Cd …

The adsorption performance and mechanisms of Pb 2+ and Cd 2+ in wastewater using MgO
modified biochar derived from crofton weed (MBCW600) are investigated. The Pb 2+ and Cd …

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 …

Soil heavy metal contamination caused by mining activities is a global issue. These heavy
metals can be enriched in plants and animals through the food chain, and eventually …

The sesame straw-derived biochar was successfully prepared via alkaline hydrogen
peroxide (AHP) pretreatment in this study. Systematic experimental characterizations, 15 …

Biochar, as a adsorbent, can remove potentially toxic elements (PTE) in water by physical
adsorption, as well as chemical interactions such as ion exchange, electrostatic attraction …
