Less than one percent of the earth’s water is easily accessible to us as freshwater and nearly half of this
water is heavily polluted with pesticides, emerging contaminants, and heavy metals due to waste from industry,
human establishments, and agriculture. This research aimed to remove these key classes of contaminants by
manipulating biochar surface area, controlling chemical composition and catalytic properties for oxidative
breakdown, adding surface complexing agents, and modifying intrinsic pore size.
