Recently, recovery and synthesis of AgNPs from electronic waste have become a vital issue among the scholars, as silver is used to coat medical appliances. For this, initially 10 g of electronic waste is crushed to form a homogeneous powder which then was placed in an over for 10 minutes at 500°C, by this any possible contaminations would be removed. After which Nitric acid (HNO3) solution is added to dissolve the silver content from the homogeneous powder. Thereafter, liquid containing silver salt was centrifuged at 6000rpm. AgNO3 is collected and dried for 24 hours at 60°C under a vacuum of 10 millibars. From the obtained dried AgNO3, 5g was added to 100 ml of ethanol (has reductive role) which is then stirred for 30 minutes. 5% PVP is added dropwise as a stabilizer to avoid agglomeration. Finally, the system was mixed at a specific temperature and time. Usually, to investigate the effects the system is timed as 30,60,90,120 minutes and the samples were synthesized at temperatures 20,30,40 and 60 °C. The AgNPs obtained at 60°C for 60 minutes were of size 400 to 450 nm which were more significant as compared to those obtained at 30 minutes and 90 minutes [59]. This method is simple and cost-effective and produces uniformly sized nanoparticles under controlled condition. However, it does require careful control of reaction parameter to prevent agglomeration .
