Biomass and PAN-based Activated Carbons for Copper Removal from Waste Printed Circuit Boards
Short Introductive summary
In this study, as one of the most promising techniques, adsorption using activated carbons was applied to evaluate the performance of adsorbents for the recovery of copper from aqueous solutions. Four biomass-based KOH-activated carbons fabricated from olive stones and almond shells with a carbon/KOH ratio of 1:2 and 1:4 w/w and three PAN-based activated carbons (KOH-activated PAN (polyacrylonitrile) with a carbon/KOH ratio of 1:4 w/w, sulfur-activated PAN with a carbon/sulfur ratio of 1:1 w/w and PAN-b-PMMA (block copolymer based on polyacrylonitrile and polymethyl methacrylate) activated using KOH with a ratio of 1:4 w/w and sulfur with a ratio of 1:1 w/w) were produced to evaluate their copper adsorption capacity and efficiency. The results obtained demonstrated a considerably higher adsorption capacity and efficiency of copper corresponding to activated carbons fabricated from olive stones and almond shells in comparison with activated carbons produced from PAN.
