Abstract: With the continual modernization, researchers and scientists are very conscious about the environmental issues. The E-waste which is relatively recent addition to the waste stream in the form of discarded electronic and electric equipment is getting increasing attention from policy makers as the quantity being generated rising rapidly. The consumption of e-waste has been exponential in the last two decades. The developing countries are facing huge challenges in the management of e-waste which are either internally generated or imported illegally as used goods in an attempt to bridge the so-called “digital divide”. E-waste contains hazardous constituents that may negatively impact the environmental and affect human health if not properly managed. On the other hand, e-waste contains up to 60 metals including platinum, gold, silver, copper, aluminium, palladium, iron and other valuable metals. Considering these two facts along with the resource management strategy has been committed to extract precious metals from Printed Circuit Board (PCB) of e-waste. In this study, Printed Circuit Board (PCB) are collected from the motherboards of waste computers and performing several reactions in a chemical lab. Al2(SO)4 has been prepared by using sulfuric acid and potassium hydro-oxide and CuSO4 prepared by using nitric acid and sulfuric acid. In this preparation process the top most priority is placed on the environment friendly issues. This study will very helpful in the proper management of e-waste and reservation of our resources which are limited.
