Removal of Cr (VI) from synthetic effluents using hydrochar from waste açaí (Euterpe precatoria Mart.) seeds as a low-cost biosorbent

ABSTRACT Chromium (Cr) is a common contaminant in aquatic ecosystems, and in its hexavalent form (Cr (VI)) can cause serious risks to human health. This study utilized açaí waste to prepare a novel hydrochar (AWR) for Cr (VI) removal. AWR was characterized by Boehm titration, point of zero charge, i...
