Abstract
A biochar is produced by co-pyrolysing an aquatic plant enriched with heavy metals with a clay mineral, and the aquatic plants themselves have high enrichment and adsorb heavy metals in contaminated water; heavy metals are in situ adsorbed, and are coated or enriched in the biochar, therefore extending the migration time of heavy metals, which are also very stable; attapulgite and montmorillonite as clay minerals are loaded in the biochar during the preparing process; heavy metals contained in the biochar play a catalytic role, and synergy with activated attapulgite, therefore increasing the reliability of the biochar, and effectively reducing the ecological effectiveness and potential risk of heavy metals in the biochar.
