Biochars were derived from wood and water caltrop shell waste for the adsorption of Cr(III) and Cu(II) in solutions. In the competitive adsorption, Cu(II) had a good affinity for the water caltrop shell and blended biochars. The blended biochar was a mixture of wood and water caltrop shell biochars. Each biochar adsorption equilibrium data fit well with the Freundlich model. The effectiveness of the adsorption of Cr(III) and Cu(II) solutions utilizing biochar is proven to be effective in continuous adsorption columns, and the adsorption performance is verified with model simulation.
