Abstract

Electronic waste is the misplaced wealth or in other words, it is the unwanted electrical equipment which is not fit for its indented use. The integrated part of e-waste, PCB, contains several types of metals which have significance in diverse ways. The removal of these metals plays a significant role because of the depletion of natural resources. The result of bioleaching of PCB produces lixiviant pool of metals and this is taken as a sample for the study. Copper has been chosen from all metals because of its augmented use and it is highly present in the PCB. The entire weight of PCB contains 30% of copper. Though there were various treatment processes for leaching metals, there is no proper removal of metals from the lixiviant pool. It was found that e-waste leachate has been disposed with no proper treatment because of the quantity and the quality present in it. But an attempt has been made to reuse the waste and thereby stopping the depletion of nonrenewable resources. Adsorption is used for the extraction process. Citrus fruits are highly used to prepare juices and medicines for indigestion. Lemon is a rich source of abscisic acid which is citrus. The wastes of lemon once used are disposed and so the waste generated by the fruit is high. The waste of lemon is activated to produce adsorbent, named as Lemon Activated Carbon (LAC) and the performance was compared with commercial activated carbon. A characteristic study was made by zeta potential, particle size analyzer, and surface area analyzer. The metals adsorption was analyzed with the help of Atomic Absorption Spectroscopy (AAS). The copper adsorption capacity for LAC was more than 85% which is not much less than CAC.
