| 英文摘要 | The metal recycling processes in the waste printed circuit boards (WPCBs) are mainly pyrometallurgy and hydrometallurgy, whereas hydrometallurgy is considered as an efficient but less environmentally friendly process. In this study, a green amino acid, glycine, was used to replace traditional inorganic acids to extract Cu from WPCBs by investigating the effects of temperature, H2O2 volume, solid-liquid ratio and glycine concentration on Cu leaching efficiency. The kinetics and thermodynamics of the leaching process were also studied. The maximum leaching efficiency is up to 94.08% when the temperature is 30 degrees C, initial H2O2 volume is 10%, the solid-liquid ratio is 1:100 and the initial glycine concentration is 1 mol/L. After leaching, sky blue crystal, cupric-glycinate, could obtain by adding absolute ethyl alcohol. The leaching process is controlled by diffusion and chemical reactions. All these results show that the green glycine could successfully replace traditional inorganic acids to extract Cu from WPCBs, providing a feasible and perspective future for industrial application. |
