From: Nanoremediation of As and metals polluted soils by means of graphene oxide nanoparticles
Influence of nGOX (A–C) and nZVI (D–F) on the available concentrations of Cd, Pb, Zn, Cu and As in the As-Metals polluted soil (AM). For each column, different letters in different samples mean significant differences (n = 3, ANOVA; P < 0.05). Error bars represent standard deviation. Under limit detection (u.l).
