Invasive plant-derived biochar for sorptive removal of hexavalent chromium in aqueous media

Abstract

Due to increased industrialization and urbanization, chromium (Cr) has been commonly used and released to the environment in a variety of industrial activities. Two primarily available valence states of chromium in the environment are trivalent chromium (Cr III) and hexavalent chromium (Cr VI). Cr(VI) is more soluble in water, causing health hazards to human beings and animals by all exposure roots
