Use of Waste-Derived Biochar to Remove Copper from Aqueous Solution in a Continuous-Flow System

The discharges from industrial processes constitute the main source of copper contamination in aqueous ecosystems. In this study, we investigated the capacities of different types of biochar (derived from chicken manure, eucalyptus, corncob, olive mill, and pine sawdust) to remove copper from aqueous solutions in a continuous-flow system. The flow rate of the system strongly influenced the amount of copper retained. For example, the adsorption...
