Removal of Copper from Bioleachate of E-Waste Using Orange Activated Carbon (OAC) and Comparison with Commercial Activated Carbon (CAC)
E-waste is a threat of India as many countries have considered India as a common litter bin for e-waste. In e-waste, the most dangerous part is its integrated unit, Printed Circuit Board (PCB) which contains numerous metals which are precious in addition to that various harmful hazardous metals were also present in it. The drawing out of these metals plays a prominence because of the exhausting natural resources and environmental damage due to its toxicity. Bioleaching of PCB is a better environmentally sound waste management method which results in a lixiviant pool of metals, and this is taken as the sample for the study. It was found that e-waste leachate has been disposed with no proper treatment because of the quantity and the quality present in the leachate. Copper being one of the most widely used metal in PCB of e-waste. Considering its higher demand, extraction especially from a waste product is more worth. Adsorption is mainly used to extraction process of copper from e-waste bioleachate. Orange peel is activated to produce adsorbent and the performance was compared with commercial activated carbon, the prepared activated carbon is called Orange Activated Carbon (OAC). The characteristic study was done using particle size analyzer, zetasizer, surface area analyzer and Fourier Transform Infrared Spectroscopy (FTIR) was done to know the molecular group. Atomic Absorption Spectroscopy was done to find out the adsorption of metals. The copper removal capacity for OAC was more than 85% which is not much less than CAC and considering orange waste management; it can be effectively used for the sorption of copper from electronic waste bioleachate.
