| 英文摘要 | Over the last decade, glycine has received significant attention as a green lixiviant, given its benign nature and selectivity. However, its application in leaching waste printed circuit boards faces limitations in production capacity. To address this challenge, the present study introduces alkaline glutamate (Glut) leaching as an alternative method. The glutamate leaching was found highly selective to Cu, Zn and Pb, and under the optimised conditions, 85.1 % Cu, 88.0 % Zn and 61.5 % Pb were extracted. Comparative analysis with glycine leaching revealed significant advantages of glutamate leaching. Glycine leaching with > 2 % solids resulted in limited Cu extraction and considerable Cu loss (30-65 %), due to the precipitation of oversaturated cupric glycinate. In contrast, 5 times higher solids content (10 %) could be accommodated in glutamate leaching. Furthermore, the Cu concentration in the leachate of alkaline glutamate leaching was found to be more than double that from glycine leaching (21.0 vs. 9.9 g/L). |
