Box-Behnken Optimization and Theoretical Study for Copper Recovery from Scrap Laptop Computer Printed Circuit Board by Malonic Acid and Hydrogen Peroxide
Abstract:Copper (Cu) is a major target in metal recovery during the recycling of scrap printed circuit boards (PCBs). Herein, we report on the optimization of parameters for the leaching of Cu from scrap PCB pieces by malonic acid and hydrogen peroxide (H2O2). Large PCBs obtained from scrap laptop computers were cut into smaller 2 cm by 2 cm pieces and de-epoxidized by NaOH treatment. The average Cu content in each PCB piece was determined by complete solubilization in aqua-regia and found to be (0.84±0.13) mg/g. An op… Show more
