The present investigation focus on the recovery of copper (Cu) ions from printed circuit boards (PCBs) by applying simultaneous treatment of leaching and adsorption, as a novel approach. The PCBs are subjected to chemical leaching using aqua regia resulted in a Cu recovery of 97.06%. The leached solution is treated for removal of Cu with activated bent clay as an adsorbent. The optimum condition of process variables is found through central composite design-response surface methodology (RSM-CCD). The maximum %Cu removal of 97.33% is obtained at the optimum operating conditions of adsorbent size of 0.04 mm, adsorbent dosage of 3.5 g.L-1 and the temperature of 80C with 0.845 desirability. This investigation is found to be an eco-friendly way to recover copper ions and does not cause any environmental issues. |
