Extraction of Tin and Copper by Acid Leaching of PCBs

Nitric acid was found suitable and used for the extraction of copper and tin at room temperature. In the leached solution suspended tin and copper nitrates were obtained. X-ray diffraction (XRD) and Energy dispersive X-ray analysis (EDAX) was done to characterize the precipitate obtained.
