Abstract

Due to the fast development of electronic waste and the gradually deficient of the modern resources, the environment is deteriorated seriously. Thus, the recycling and utilizing of electronic waste becomes an important research area in modern scientists. In the present paper, the authors employ H2SO4 acid and H2O2 blend solution and C2H5OH-KBr-K2SO4 extraction solution to gradually departure the gold from electronic waste. What's more, the authors use atom absorption spectra and XRD methods to analyze the gold solution extracted using the above method. It is concluded that using H2SO4 acid and H2O2 blend system is a 40% higher efficiency compared with the traditional method.
