Abstract
Electronic waste is the waste electrical and electronic equipment which is not fit for its original intended use. Out of which printed circuit board (PCB) has approximately ten different metals with it, while the percentage of metals present in PCB differ according to the instruments. The extraction of these metals play a major role because of the depleting natural resources. The lixiviant pool of bioleaching was chosen for the study for the extraction of metal. Copper has been chosen among all metals because of its increased usage and high content of about 30% on the PCB. Adsorption is used as a key tool in the extraction process. An attempt has been made to minimise waste and convert them into activated carbon. The activated carbon synthesised with banana peel (BAC) could replace commercial-activated carbon (CAC) which could reduce the depletion of natural resources. The copper adsorption capacity for BAC was more than 80%. The results of atomic absorption spectroscopy (AAS) indicated that banana peel is an effective adsorbent of copper from electronic waste leachate which results in waste minimisation.
