Total respective biosorption of ANZECC metals by biochar and biomass, and metalloids by Fe-treated biosorbents.

<p>Biosorption of metals (Al, Cd, Cr, Cu, Pb, Mn, Ni, and Zn) by (a) biochar and (b) biomass and biosorption of metalloids (As, B, Mo and Se) by (c) Fe-biochar and (d) Fe-biomass. Initial pH of 2.5, 4 and un-manipulated (7.1) are shown by solid, dashed and dotted lines, respectively. Error bars show standard errors
