Compared with graphene oxide (GO), r-GO (the reduced form) has a lower adsorption capacity for heavymetal ions and, therefore, generates concern over the release of adsorbed contaminants when GOadsorbent is discharged into a reducing environment. This study reveals that the maximum adsorptioncapacity of Pb(II) on GO and r-GO was 937.65 and 92.99 mg g 1 respectively. GO was reduced to r-GO bysulfide, causing 2.59–6.46% of the adsorbed Pb(II) to be released and was stably dispersed as a Pb(II)-oxidative debris (OD) complex. Our results provide valuable information about heavy metaltransportation in environments containing GO under different redox conditions.
